2 78 VACUUM FILTRATION Introduction Vacuum filtration is used primarily in microbiological and analytical procedures that involve collecting a particulate (bacteria, precipitate, etc.) from a liquid suspension. Liquid poured into a funnel passes through a filter, which retains the particulate, and filtrate can be collected into a filter flask, directly or via a vacuum manifold. Applying vacuum reduces process time compared to gravity flow. Advantec supplies a wide range of vacuum filter holders and accessories. Select from glass, polysulfone, or stainless steel assemblies with funnels holding from to 000 ml. See facing page for more details on supports. Typical Applications DNA/RNA hybridization, protein binding, Coliform, yeast, Colony hybridization, receptor binding studies and gravimetric mold, total bacteria, procedures requiring analysis sterility testing larger filtration area Recommended Models Glass with glass frit KG KG KG 7 KG 90 Glass with stainless steel - KGS KGS 7 KGS 90 support Glass with PTFE support - - KGT 7 - Glass with all-ptfe seal - - KGT 7 TF - All-glass assembly GFA GFA 7 - GFS GFS 7 - GFT 7 Phase/Fraction collector - - P/FC - P/FC Polysulfone - - KP 7 - Stainless steel - - KSF 7 - Filter Specifications Membrane diameter mm mm 7 mm 90 mm Filtration area. cm. cm 9. cm *. cm * See individual models for exceptions
