Vacuum Filtration Systems for 47mm Membrane Filters

BGB Filter Funnels and In-Line Systems are made of durable polypropylene and are therefore practically indestructible. Filter Funnels have a threaded filter base that connects directly to any receiver with GL45 threads. It uses any 47mm diameter membrane. To use, connect the filter base directly to your vacuum source using one of the six tubing adapters included with each unit. Polypropylene construction is ideal for mobile phase filtration, degassing, and culture media filtration. Choose from 1L and 2L funnel volumes.

The In-Line system uses the threaded base of the funnel system but replaces the funnel with the in-line filter cap. Tubing is connected to the filter cap and draws liquid into the system from any container. This minimizes atmospheric exposure and handling hazards. The polypropylene fluid path uses any standard 47mm membrane.

Choose your own 47mm filter paper based on your filtration needs.
