Gravi-Seal™ Analytical Funnels

By GE Osmonics
Gravi-Seal™ Analytical Funnels

A two-piece polysulfone analytical funnel with a unique gravity sealing design. No clamps or locking devices to manipulate. Instead, the Gravi-Seal™ allows easy one-handed operation without danger of filter bypass or sample leakage. More economical than glass, stainless steel or magnetic funnels with no costly replacement parts. Takes standard 47mm membranes.

Sturdy polysulfone funnel and base are autoclavable and chemically resistant. Funnel is graduated to 350mL in 50mL intervals. A #8 silicone stopper mounts in a standard 1 liter filtering flask for individual tests or in multiple place manifolds for concurrent testing.
