Vacuum Manifold Series

VacuumManifold_HousingsProductGroup_HomepageSlider

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.

Cobetter lab stainless steel vacuum filtration manifolds are available in 3-branch or 6-branch unit configurations. The multi-branch vacuum filtration manifold is designed to filter several samples at the same time using a vacuum filtration pump attached directly to the manifold.

 Each vacuum filtration station has an individual control valve for maximum flexibility

 Stainless steel manifold construction (SS 316L) ensures a high level of chemical resistance and is easy to clean
