47mm Gravi-seal Analytical Funnel Filter Holder

The Gravi-Seal Analytical Filter Holder combines a number of key features and benefits, making it a tremendous value. To begin with, the funnel has only two pieces. There are no clamps or locking devices to manipulate. A unique gravity sealing design allows for one-handed operation with no danger of filter by-pass or sample leakage when using depth filters. And it is stable and very solid with no costly replacement parts. It all adds up to the easiest and most cost-efficient analytical funnel available.

Gravi-Seal analytical funnels are available in polysulfone for aqueous samples. The polysulfone unit is autoclavable and chemically resistant for cell culture and microbiological applications. The No. 8 stopper mounts in a standard 1-liter filtering flask for individual tests or in three- and six-place stainless steel manifolds for multiple tests to run concurrently.
