Whatman™ Polycap GW (Ground Water) capsule filters from Cytiva are specifically designed for sample preparation of ground water samples for dissolved metals analysis. The in-line design with stepped hose barbs and hydrophilic polyethersulfone (PES) membrane make it easy to use for field sampling.
Stepped hose barb fittings allow for connection directly to outlet of a sampling pump with various size tubing
Effective filtration surface area of 600 cm² to ensure rapid sample collection
PES filters in thermally fused housing eliminate sample contamination that could come from glues, adhesives, metals, epoxies, or extraneous materials
Lot number printed on each unit for traceability supports use in regulated field sampling methods such as EPA Method 3005 for ground water analysis
Well suited for ground water sampling as a dissolved metals filter
PES filter for ground water sampling
The United States Environmental Protection Agency (EPA) and other environmental protection agencies have protocols specifying support of ground water sampling with a 0.45 µm filter prior to analyzing dissolved or suspended metals (EPA Method 3005).
Whatman™ Polycap GW PES filter capsules support dissolved metals filtering during field sampling and can be connected directly to a sampling pump. These filters are appropriate for use in EPA methods that specify use of a 0.45 µm filter.
