Geotech dispos-a-filter™ PES/PP Filter Capsules

Disposable Filter Capsules

The Geotech PES (Polyethersulfone) dispos-a-filter™ is the easiest and most cost efficient way to prepare water samples for trace metals analysis. Geotech's dispos-a-filter™ capsules feature self-contained absolute rated pore size membranes that are scientifically designed to meet U.S. EPA filtration regulations. When field or laboratory filtration is required, the dispos-a-filter™ is perfect for maximum flow capacity and retention of particulate matter.
