4 Generator - Griffin Beaker Arsine Generator Designed for multiple arsenic determinations. A sample containing arsenic is placed within the flask and converted to arsine gas. Hydrogen sulfide is removed from the sample as the gas is generated by lead acetate-impregnated glass wool packed within the scrubber cavity. The absorber tube, containing the reagent silver diethyldithiocarbamate, absorbs the arsine gas and forms a red complex. This product is transferred to a cuvette, and its visible spectrum is then recorder on a colorimeter or spectrometer. Size 12 pinch clamp for 12/2 joint between the scrubber and absorber tube is available as an accessory.

7 4 BOTTLES CYTOSTIR Stirred Bioreactor for Microcarrier Cell Culture The CYTOSTIR line of double sidearm stirred bioreactors for microcarrier cell culture has been completely redesigned to improve performance and enhance interchangeability. CYTOSTIR bioreactors are available in nine sizes ranging from 100 ml to 36 liters. The borosilicate glass flasks have two large sidearms with screw cap closures that allow easy sampling. The dome in the center of the flask base prevents microcarriers from accumulating directly under the stirring blades. The large, height adjustable Teflon stirring blades are designed to provide maximum stirring efficiency to keep microcarriers in suspension at the slow stirring speeds required for tissue culture. During stirring, cultures contact only borosilicate glass and Teflon. All one liter and larger size flasks have anti-drip pour lips and polypropylene caps with sealing rings. All CYTOSTIR bioreactors and components are completely steam autoclavable.

29 26 CONCENTRATORS Kuderna-Danish and Condensers Evaporative, Kuderna-Danish, with Graduated Concentrator Tube Developed in the laboratories of Julius Hyman and Company for the concentration of trace amounts of sample dissolved in organic solvents. It is very useful in sample preparation before analysis with solvents such as petroleum ether or hexane. Preparation involves filling the flask to between 40 to 60 percent of capacity. To prevent sample loss initially, the column should be pre-wet with about 1 ml of the solvent used in the concentration. The column is designed to speed evaporation with reduced hold-up. The charged assembly should be placed over a vigorously boiling water bath. The water level should be maintained just below the lower joint and the apparatus mounted so that the lower rounded surface of the flask is bathed in steam. The final sample remains in the lower tube for further analysis. Lower tube is graduated. Complete with polyacetal clamp. Tube Graduations Flask Tube x Overall Kontes Cap. Cap. Subdiv.

The shape of the body allows easy removal of desiccant materials. Covers and bodies are interchangeable in the same size. A simplified TS 2 mm stopcock valve assembly for controlled vacuum type desiccators has replaced former sleeve valves. When properly greased, it should hold a vacuum of 29 inches of mercury for twentyfour hours. Through elimination of the sleeve, the current stopcock design minimizes chipping or marring of critically ground finishes during cleaning and assembly. The valve is secured to the desiccator lid by a neoprene grommet located in the knob of the cover. One end of the valve is equipped with a tapered stem for firmly inserting into the grommet. With this style, an accidental bump would be more readily absorbed than with styles having sealed assemblies. Opposite stem is tooled with a hose connection to accept 5/16 inch I.D. flexible tubing.

44 SPE - Filter Dome SPE Disk Glassware and Manifolds All SPE Manifolds are supplied with three-way valves that allow the venting to atmosphere of each station without affecting the vacuum in the rest of the system. SPE Manifolds are manufactured from corrosion resistant stainless steel. Valves have stainless steel bodies with PTFE plugs. The SPE Funnels have a sharp edge on the bottom inside diameter that, combined with the stronger spring in our aluminum clamps, minimizes any horizontal capillary action of the sample and solvent into the disk. Extracted samples can be collected directly into K-D concentrator tubes, EPA water analysis vials, sample vials and test tubes. PTFE-coated stainless steel support screen reduces the possibility of sample-to-sample cross contamination compared to the traditional glass frit. The PTFE coating also protects the support screen from corrosion caused by acid preserved samples. The SPE Support Bases have a specially designed internal surface that reduces dead volume and minimizes holdback of the extracted analyte. Get the most out of using 3M Empore TM Extraction Disks with our line of SPE Glassware and Manifolds. They have been specially designed for use with solid phase extraction disks to give you the highest possible recoveries of extracted analytes from your drinking water, surface water and waste water samples.

63 60 NMR Choose Kontes Brand NMR Tubes Concentricity Kontes Brand NMR Tubes Kontes has provided superior quality products for the nuclear magnetic resonance spectroscopy market since Our NMR tubes are manufactured from KIMAX ASTM Type I borosilicate glasses and their performance is assured by state of the art manufacturing and inspection processes for wall thickness, concentricity, and camber. Types of Tubing KG-33 is a KIMAX ASTM Type I, Class A borosilicate glass with a high degree of thermal shock resistance and low coefficient of expansion. This is particularly suitable for use where large temperature variations are applied. KG-33 is ideal for use in various sealing techniques. N-51A is a KIMAX ASTM Type I, Class B borosilicate glass which also has a comparatively low coefficient of expansion, but is not suitable for sealing techniques. NMR Tube Specifications Wall thickness is closely monitored to assure that our customers consistently get reproducible results. If the I.D. is too large, vortex plugs and coaxial inserts can slip; if the I. D. is too small the plug could break the tube. If the O.D. is too small, the tube will wobble causing modulation sidebands; if too large the inside surface of the probe insert may be contacted causing damage. Wall Thickness Camber Concentricity is the measure of wall uniformity and is determined with gauges. Recorded as Total Indicator Reading (T.I.R. or the absolute variation in wall thickness) as measured at the ends of a tube during rotation, lower readings yield better tubes. Nonconformity to concentricity tolerances causes portions of the sample to be exposed to differences in the magnetic field leading to undesirable modulation sidebands. Camber is the measure of straightness of a tube and is determined with gauges by measuring the deflection at the middle of a rotating tube held at the ends. Recorded as Total Indicator Reading (T.I.R. or the absolute value of the deflection range), tubes with deviations <0.002 (0.051mm) in camber can be expected to spin reliably. Higher frequency NMR spectrometers require stricter tolerances for the camber of tubes. We guarantee our tubes to meet stated dimensional specifications and to produce accurate results according to the field strength of the NMR spectrometer.

67 64 NMR Threaded tubes facilitate reaction studies and sample storage Valved tubes make it easier to study difficult compounds Specialty NMR Tubes Valved 5mm Tubes KONTES Brand valved NMR tubes are designed to improve sample handling during the investigation of volatile, air-sensitive or toxic compounds. Condensation of sample occurs directly into the NMR tube through the use of vacuum techniques. A special KONTES HI-VAC valve maximizes sample recovery and permits resealing as opposed to the permanent seal-off method. The HI-VAC valve features a borosilicate glass body and PTFE plug so that the sample is in contact with inert materials. The valve is greaseless thereby eliminating the risk of sample contamination. The rotationally symmetrical design, with two lateral ports located near the valve seat, permits use at higher temperatures. A glass tube with a Viton o-ring seal is used to connect the valved NMR tube to a vacuum system. All sizes are precision grade and suitable for use in instruments with field strengths greater than 360 MHz. Tube Kontes Wilmad Diam.

79 76 TISSUE/CELL Mini-Bomb - Ultrasonic Cell Disruption Chamber, Mini-Bomb Cell Disruption Without Heat Build-up From Friction The KONTES Brand mini-bomb cell disruption chamber processes samples ranging in size from 1 to 15 ml. Cells are disrupted with this apparatus through the sudden depressurization of cell suspensions. First, the mini-bomb is loaded with 1 to 15 ml of a cell suspension. Next, it is pressurized with air, nitrogen or carbon dioxide (see Figure 1). After the cells have equilibrated, the pressure is released and the cells rupture. The result is a uniform homogenate of whole cells and sub-cellular components. To avoid aerosols generated in this process, the gas escaping from the mini-bomb during decompression should be directed into a gas washing bottle as illustrated in Figure 2. The gas washing bottle should contain an acidic solution. This method of cell disruption eliminates the heat build-up associated with mechanical and ultrasonic cell disruption. The cells are actually cooled by the expanding gas. Pressure and equilibration time can be varied to control the extent of cellular disruption. For example, a short treatment at moderate pressure will rupture the outer cell membranes leaving the nuclei intact. After separating these fractions a second treatment can be used to rupture the nuclei. Figure 3 shows the effect of pressure and number of pressurization cycles on various cell types. Valve Figure 1.

80 Principle of Operation Dounce Tissue grinders produce homogenates by a combination of shearing and compression actions. The tissue sample is progressively ground (sheared) into smaller pieces at the rounded end of the pestle as the spinning pestle is lowered into the tube. As the pestle is forced lower into the tube, the sample is displaced and forced between the straight outside wall of the pestle and the inside wall of the tube, compressing the tissue cells until they rupture. When the tube is pulled away from the pestle, a slight vacuum is created that pulls the sample back past the compression area, resulting in an additional homogenization stroke. The degree of homogenization is controlled by the clearance between the pestle s and tube s cylindrical section (radial distance usually inches), the rotational speed of the pestle and the number of compression strokes made. There are three basic types of tissue grinders: Dounce, DUALL and Potter-Elvehjem. In choosing the correct tissue grinder for a particular application, there are two rules that apply: 1. Conically shaped pestles homogenize better than pestles with a rounded shape. 2. Ground glass to ground glass surfaces homogenize better than smooth glass to smooth glass or PTFE to smooth glass. Using these rules, a glass DUALL tissue grinder produces the finest homogenate while a glass Dounce will produce a relatively coarse homogenate.

116 Glass Properties Technical Info. 113 IDENTIFICATION OF KIMBLE GLASSES Information as to the type of glass from which a specific piece of apparatus is made is often required. The purpose may be to determine the glass with the best possible chemical durability, or the glassblower may wish to seal onto existing pieces of apparatus or create an entirely new piece, composed of several other parts. There are three relatively easy tests to determine glass type within your own laboratory. Density Test The densities of the Kimble laboratory glasses are: KG g/cm 3 N-51A 2.33 g/cm 3 KG g/cm 3 KG-35 may be differentiated from N51A by the seam line on the surface of the item, and identifying marks on the bottom from the blow molding process. N51A will have neither of these characteristics. The other glasses are readily identified by the sink/float method. Small pieces of the glass or glasses to be checked are dropped into two liquids: A) 2.30 specific gravity (Mix 354 ml of triethylene glycol and 646 ml of s-tetrabromoethane.) B) 2.44 specific gravity (Mix 264 ml of triethylene glycol and 736 ml of s-tetrabromoethane.) Liquid Float Sink 2.30 KG-33 N-51A (also KG-35) 2.44 KG-33 N-51A (also KG-35) Before using these liquids, their material safety data sheets should be consulted for proper handling precautions. (The liquids should be stored in glass stoppered containers, preferably amber, at room temperature. Spillage should be avoided because the liquids damage painted surfaces.) Differential Expansion (Dual Fiber) Test Differences in the linear coefficients of expansion of the laboratory glasses may be used as a means of identification by lampworking; drawing a fiber with a standard known glass and observing the absence or presence of a curvature in the fiber. Physical Properties of Glass Glass is an inorganic product of fusion that has cooled to a rigid condition without crystallizing and, therefore, has no melting point as such. There are, however, four temperatures that are of interest to the glassblower. They are: 1. The Working Point the temperature at which glass has a viscosity of 10 4 poises. At this temperature, glass is soft enough for most lampworking or sealing operations. 2. The Softening Point the temperature at which glass has a viscosity of poises. In this temperature range glass will deform noticeably under its own weight: ASTM C The Annealing Point the temperature at which the internal stress caused by rapid cooling from lampworking or forming temperatures may be substantially removed in a matter of minutes. It is determined by measuring the elongation rate versus temperature of a fiber of glass under conditions prescribed by ASTM Designation C 336. The values given herein are typical for production glasses. 4. The Strain Point the temperature at which the internal strain in a glass is substantially relieved only after a matter of hours and not at a commercially desirable rate. It is determined by extrapolation of annealing point data for fiber elongation: ASTM C 336.

117 114 Technical info. Care and Handling of Glassware Glassware Safety You play by common, ordinary, everyday rules, the kinds of things you d do naturally if you just took time to think about them: 1. Don t get cut it hurts you and your productivity. 2. Don t drop glassware avoid the bruises that lead to breakage. 3. Don t use chipped or broken glassware it s dangerous and breaks more readily. 4. Don t mouth pipette you could inhale a toxic substance, burn your mouth, or cut your lip. 5. Don t leave pipets sticking out of beakers or flasks an invitation for an accident. 6. Insert tubing carefully. Use a protective towel for your hand and lubricate the tubing. 7. Dispose of broken glassware in a special receptacle. 8. Carry large containers carefully, using a bottle carrier. 9. Clean and rinse glassware very well with deionized water, then let it drain dry on a clean, lint-free towel. To back up the rules, you need a formal laboratory safety program. It begins with a written safety policy, a safety committee, and regular safety inspections. That way, you can investigate accidents thoroughly, keep a record and analysis of them, and promote safety awareness all the time. It could lead you to the best safety record ever. Care and Use Cleaning Methods Care should be exercised when using most cleaning solutions as they can cause skin irritations or severe burns on contact. Dilute solutions become concentrated as the water evaporates; therefore, always flush the exposed area immediately with large quantities of water. The list of methods given here is by no means complete, but offers a fairly wide variety and should cover all the usual contaminants, as well as the more important special cases. Frequently it is desirable to give glassware a preliminary rinse or soak with organic solvent to remove grease, followed by a water rinse. The rinsing with water must be done thoroughly if acid will be used later to clean the glassware. Unless autoclaving is necessary, glassware should be cleaned as soon as possible after use to avoid setting and caking of residues. Pipets, for example, may be placed in a convenient jar containing a weak antiseptic solution, immediately after use. Autoclaving is necessary to disinfect glassware that may have been used to contain potentially dangerous biological fluids. There is a wide variety of cleaning agents available that will remove surface contaminants such as silicone and other organic and biological residues, blood residues and other contaminants that may interfere with trace analyses. These cleaners are available in biodegradable, phosphate-free and chromium-free formulations if desired and can be obtained from laboratory supply houses. NOTE: If wiping or other mechanical cleaning action in necessary, it should be done gently using non-abrasive cleaners and wiping materials. The use of abrasive materials will damage the glass surface, degrading its inherent strength. There are some specific contaminants that may require specialized cleaning methods, and some are given here: 1. Permanganate stains. Use a mixture of equal volume of 3% sulfuric acid and 3% hydrogen peroxide. 2. Iron stains. Use a solution containing on part hydrochloric acid and one part water. 3. Bacteriological material. Glassware should be soaked in a suitable disinfectant solution or steam autoclaved followed by cleaning with a suitable agent. CAUTIONS: Before using any cleaning solution, refer to its Material Safety Data Sheet for precautions to be observed during use. Some of the cleaning materials used may leave trace residue unless rinsing process is carried out thoroughly. While such traces may not be harmful if the object of cleaning is to prepare the glassware for calibration, they can give trouble in certain laboratory operations. When glassware is to be calibrated, the final rinsings must be distilled water. If an article is to be dried after cleaning, as is necessary for all vessels marked To Contain, ethyl alcohol or acetone (American Chemical Society Specification) may be used. Drying may be hastened by blowing clean, dry air into the vessel (or sucking the air through the vessel). Efficient air filters must be provided to remove any particles of oil or dirt from compressed air. Drying should be done in a fume hood. For a complete listing of Kimble, Kontes and Chase Brand

118 Care and Handling of Glassware Technical Info. 115 Care and Use Cleanliness of Apparatus The usual criterion of cleanliness of glass apparatus is uniform wetting of the surface by distilled water. Certain contaminants, especially grease, adhering to the walls prevent them from being uniformly wetted, and there is a tendency for water to collect into drops. Imperfect wetting causes irregularities in capacity of volumetric glassware by distorting the meniscus, and also by affecting the volume of the residue adhering to the walls after emptying instruments calibrated to deliver the indicated volume. Even when the surface of the vessel is uniformly wetted, variations in the apparent capacity still may occur, due to contamination of the liquid surface by minute quantities of fatty or other organic substances which produce a change in surface tension affecting the shape of the meniscus. The cleaning, rinsing and drying, therefore, must be carried out in such a way as to prevent this from happening. The choice of the procedure to be used in cleaning glassware depends on the nature of the contaminant. In many cases special reagents or methods must be used to remove a particular substance. Before listing the more important methods, it is desirable to make a few general statements. Glass Glasses used in chemical apparatus have excellent resistance to acids, except hydrofluoric. Strong alkaline solutions, such as hot caustic solutions, will attack any glass if contact is prolonged. This is true even though a particular glass may not exhibit any visible effect, due to the solubility of the reaction products. Dilute detergent solutions, up to about 2% strength, will have no serious effect on the glass, unless the glass is exposed for unnecessarily long periods or the detergent is allowed to dry on the glass. Colored Graduations The scales and inscriptions of many items of Kimble glassware are colored by staining a thin layer of the glass. Since the colored portion is of the same composition as the glass object, the resistance to chemical attack is the same as that of the rest of the glass. Here, the color can be removed only by dissolving a layer of glass from the surface. Some Kimble volumetric glassware has fused on, ceramic enamel printed lines and inscriptions. These fused-on enamels are quite resistant to acids and alkalies. In most cases they should last as long as the piece of apparatus if cared for properly. However, by their nature, they cannot be as resistant as the ware to which they adhere. Consequently, the graduated lines should not be subjected to prolonged immersion in acids or alkalies. Whenever the lines are wetted by reagents, they should be rinsed as soon as conveniently possible. Safety Precautions With many pieces of glassware, it is necessary or desirable to fill by suction when cleaning. Do not suck up acid or other cleaners by mouth. In fact, do not pipette by mouth at all. Use hand held, manual or electronic pipetting aids. Abrasives Do not use abrasives on glassware, particularly volumetric ware. The surface will be marred in time, and the resultant scratches may prevent proper drainage or act as resting places for adulterants which will be difficult to remove. Water for Rinsing When preparing a piece of glassware for calibration, rinsing with tap water should be followed by a thorough rinsing with distilled water. Sufficient material may be deposited on the surface by tap water to cause erratic results, particularly with small items, even though water wets the surface uniformly. Even in ordinary cleaning processes, the use of deionized water is recommended. Adherent Organic Residues Never attempt to remove such residues by the application of direct heat. Permanent strains may be introduced and, what is more important, the calibration of volumetric apparatus may be changed.

119 116 Technical info. Care and Handling of Glassware Care and Use Stopcocks with Plugs Made of Polytetrafluoroethylene (PTFE) Kimble stopcock plugs of PTFE are made of the most chemically inert material in laboratory use today. Only a few chemicals have any effect on PTFE and these only at elevated temperatures and pressures. The material is extremely tough, durable and heat resistant, with practically zero moistureabsorption. It remains non-brittle even at sub-zero temperatures. To obtain maximum performance from your stopcock plugs of PTFE observe the following hints: 1. To clean new plugs, carefully disassemble, lift plug free of glass barrel, and rinse all parts of plug and barrel in acetone. After drying, reassemble and the stopcock is ready for use. (Do not use abrasive materials to clean either plug or barrel at any time.) 2. The washer of PTFE must always be placed adjacent to the end of the glass barrel, to secure minimal friction when turning. When properly tightened, the plug will be slightly more resistant to turning than a lubricated glass plug. 3. Plugs of PTFE can be easily scored around the bore if rotated when solid particles are lodged between plug and barrel, or project beyond mating edges of glass parts. Once scored, the plug may leak. 4. Do not use a stopcock plug of PTFE on a vessel used for long time storage of liquids known to attack glass, since the surface of the barrel may become roughened, and leakage may occur between the plug and barrel causing a potential safety hazard. 5. If plugs of PTFE are used with liquids corrosive to glass, such as alkalies, rinse the stopcock thoroughly with water after use. Do not allow the liquid to evaporate. The concentrated solution remaining will attack the glass surface: and the eventual solids may also mar the surface of PTFE if the plug is then rotated. Care and Use Ground-Glass Surfaces Ground-glass joints and stopcocks should never be used when dry. Although groundglass surfaces seal well without the use of lubricants, it is advisable to lubricate them to prevent sticking and breakage. Ground surfaces must be cleaned prior to lubrication dust, dirt and particulate matter may score the surface and cause leakage. Different lubricants are used for these operating conditions: Silicone grease for high temperature and high vacuum Glycerin for long term reflux or extraction Hydrocarbon grease for general laboratory use Lubricating Ground-Glass Joints 1. Lubricate joints that must be airtight and when glassware contains strong alkaline solutions. 2. Lubricate only the upper part of the inner joint. A properly lubricated joint appears clear, without striations. 3. Do not allow grease to come in contact with vapor or liquid and cause contamination. Lubricating Stopcocks Spread two circular bands of grease around the stopcock plug. Insert the plug into the barrel and twist several times until the assembly is completely transparent. Be careful not to use too much lubricant or the bore will become plugged. Care and Use HI-VAC TM PTFE VALVES 1. Valves are assembled with Viton O-rings, suitable for use with oxidizing and NON- POLAR compounds at temperatures from -23 C to 204 C. 2. All elastomers have outgassing rates higher than glass. Long pump-down periods will typically reduce these rates by a factor of ten. Vacuum systems using PTFE valves normally operate at pressures up to 10-6 mm Hg. Heating of this valve during pumpdown with an air heat gun will improve ultimate vacuum. 3. O-rings should be lubricated with a thin film of vacuum grease to prolong life and reduce leakage by allowing the o-ring to slip easily along the tube. Excess grease should be thoroughly wiped off. 4. Any leakage across the o-ring stem seal occurs mainly on the inward movement. Turning the stem in and out during pump-down helps evacuate the space between the two stem o-rings. One o-ring may be removed if preferred, improving performance under some conditions. 5. O-rings may be removed from the stem by pushing the o-ring into the groove with thumb and forefinger, distorting ring sufficiently to form a small loop which can be picked up and the o-ring pulled off of the stem without damaging surfaces. Reg. T.M. E.I. DuPont Co. 6. When not in use, store in a dust-free area with plug loosened within the glass barrel. Although tough and unbreakable, PTFE is softer than glass and has a tendency to conform to the glass surface, including eventual expansion into the hollow parts of the barrel.

120 Care and Handling of Glassware Care and Use Recommendations Technical Info. 117 A.TO AVOID SERIOUS AND PERSONAL INJURY, AVOID ABRASIONS - An abrasion reduces the strength of glass, making it more susceptible to breakage under impact and/ or thermal shock. Thermal shock may result from sudden changes in temperature or use on either a burner or hot plate. Serious injuries could result if breakage occurs while glass holds heated and/or corrosive liquid. B. RECOMMENDED GLASSWARE CLEANING AND HAN- DLING PROCEDURES PROPER CLEANING PROCEDURE 1. Washing machines may be used. Support racks on the washer must be well maintained. The support pins should be coated with a nonabrasive material to prevent metal to glass contact and scratching. 2. For manual washing, use only plastic core brushes that have soft non-abrasive bristles. Soft, clean sponges or other wiping materials may be used. DO NOT USE THESE BRUSHES OR WIPING MATERIALS WITH ABRASIVE CLEANERS. Keep them clean. Scotch Brite and similar scouring pads will scratch glass and should not be used. 3. Inspect the glassware before each use and discard if scratched on inner surfaces, chipped, cracked or damaged in any way. D. HEATING GLASSWARE 1. Use wire gauze when heating over open flame. 2. Use either low or medium heat settings when using a hot plate. High hot plate settings will cause excessive localized heating of the glassware and will eventually cause breakage and possible injury. 3. Do not heat glassware designated as heavy duty unless recommended by manufacturer. Even though these items have added mechanical strength, they are more susceptible to breakage from thermal stock when heated. 4. Do not allow the contents of the container to boil dry as this may induce permanent stresses that will eventually cause breakage. Discard containers that have been boiled dry. DO NOT evacuate or pressurize unless recommended in the current Kimble Chase Laboratory catalog. E. CENTRIFUGE TUBES RCF values can be significantly reduced if the glass tubes have been scratched or otherwise physically abused resulting in surface damage and lowered glass strength. Refer to the current Kimble Chase Laboratory catalog. 4. Many commercial glass cleaners are available. Follow the manufacturer s directions for the use of these products since some are corrosive and can damage the glass. 5. Organic solvents are acceptable cleaning agents when conditions warrant their use. IMPROPER CLEANING PROCEDURE: 1. Do not place metal or other hard objects, such as spatulas, glass stirring rods, or brushes with metal parts, inside the glassware. This will scratch the glass and cause eventual breakage and injury. 2. Do not use strong alkaline products and hydrofluoric acid as cleaning agents, they are glass dissolvers and can damage the glassware and eventually cause breakage which can result in injury. 3. Do not use any abrasive cleansers, including soft cleansers (i.e. Ajax, Comet, Old Dutch, Soft Scrub, etc.), as these will scratch the glass and cause eventual breakage and injury. 4. Do not place hands inside glassware while wearing any jewelry, particularly diamond rings, as these will score the inside of the glassware and eventually cause breakage and injury. 5. Do not heat glassware to temperatures (>800 F) needed to burn out carbon residues. This will result in the introduction of permanent stresses in the glass that will eventually cause the glassware to break resulting in possible injury. C. AVOID IMPACT - Glass will break as a result of impact. Use care when handling to avoid impacting hard objects, such a spigots, other glassware, counter tops, etc. Products see our website at
