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 processtime compared to gravity flow. Advantec supplies a wide range of vacuum filter holdersand accessories. Select from glass, polysulfone, or stainlesssteel assemblies with funnels holding from 22 to 1,100 mL.
