Analytical Filter Holder

Overview

The GVS analytical filter holder features a Gravi-Seal™ gravity sealing design and is compatible with 47 mm depth filter discs. It enables one-handed operation while effectively preventing filter bypass and sample leakage. The funnel consists of only two components and requires no clamps or locking devices, ensuring simple and convenient use.

Made of durable and impact-resistant polysulfone material, the unit offers excellent chemical resistance and is fully autoclavable. It is ideally suited for cell culture, microbiological testing, and a wide range of laboratory filtration applications.
