2 Determination of total protein content: Determination of Kjeldahl nitrogen The behr equipment for determination of Kjeldahl nitrogen offers the user a complete individually configurable solution for the laboratory. Sample Digestion Units The sample digestion units of the behrotest InKjel line are provided with powerful infra-red heating elements. The quality and positioning of the infra-red heating elements guarantee the user reproducible heating phases and digestion temperatures at all sample positions. This also pertains to the twelve sample digestion unit, in which the samples are arrayed in two rows of six each. Direct irradiation of the samples by the infra-red sources eliminates the painfully slow warm-up phase associated with conventional heating block units. InKjel 625 M Thus, the behrotest InKjel is the ideal rapid digestion unit for the Kjeldahl nitrogen determination and other high temperature sample digestions. Steam distillation units The behr steam distillation units of the S model series are the optimal complement to the InKjel rapid digestion units. Depending on the user s requirements, he may choose between one manual and two automatic steam distillation models. These are similar in concept, but differ in the level of automation and convenience features. The top-of-the-line model, the behr S 5, is designed to accept an external titrator. All behr steam distillation units have the following common features: Powerful and fast Practical and user-friendly Exemplary safety and reliability Sturdy chemically resistant stainless steeel housing Practical quick-release vessel clamp permits easy use with right or left hand Especially simple menu-driven operation of the programmable apparatus by means of one single control knob InKjel 625 P Fume exhaust system The two-stage behrosog fume exhaust system condensate trap plus neutralization stage keeps all acid fumes completely out of the environment. Titration stations The behrotest STI manual titration station or an automatic titrator provide for reliable, safe and rapid titration into complete the nitrogen determination. behrosog 2 2

3 behrotest InKjel Infra-red Rapid Digestion Units The basic units in the behrotest InKjel model series hold insertable frames for different combinations of vessels: 6 reaction vessels with 250 ml capacity in InKjel 625 (M or P) 12 reaction vessels with 250 ml capacity in InKjel 1225 (M or P) 4 reaction vessels with 500 ml capacity in InKjel 450 (M or P) 4 reaction vessels with 750 ml capacity in InKjel 475 (M or P) If required, the user can re-equip his system himself very easily with different digestion boxes (insertable frame with suction extraction apparatus) for other sample glassware. The behrosog process suction system is available to extract vapours during digestion. All InKjel systems are completely equipped with tiered console, suction system, insertable frame and digestion glass vessels.
