Gravi-Seal Analytical Filter Holder

The Gravi-Seal autoclavable 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.
