Water Sample Filtration

The Geotech dispos-a-filter™ is a disposable, self-contained filter capsule composed of a filter medium encased in a polypropylene plastic housing that can be connected in-line to a sample delivery system, such as a bladder or peristaltic pump. Different pore sizes and capacities are available.

Geotech geofilter™ Flatstock Filter Membranes are used in plate-filter assemblies for trace metals analysis of water. Geotech Flatstock Filter Membranes are designed to be used with Geotech inline filter holders. The uniform pore size, and minimization of adsorptive losses from the sample improve the precision and accuracy of the analytical data. Many materials, pore sizes and diameters are available.

Geotech Polypropylene and Polycarbonate In-Line Filter Holders are compatible with a wide range of chemicals. The low cost Geotech Aluminum In-Line Filter Holder is ideal for organics and pesticide testing.

Geotech Acrylic In-Line Filter Holders are recommended for trace metals analysis. 142 mm filter membrane size version is available.

When a power supply for pressure is unavailable and in-line filtration impractical the manually operated Geotech Barrel Filter Holder is the ideal solution. It uses a 0.45µm, 102mm diameter flatstock filter membranes.

Geotech Stainless Steel In-Line Filter Holders are made from #316 stainless steel and designed for autoclaving when used for organic analysis. The Geotech PFA In-Line Filter Holder is designed for filtering small volumes of sample water for organic analysis. Wetted surfaces are made with PFA fluoropolymer for maximum chemical compatibility.
