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 ell suited for ground water sampling as a dissolved metals filter Whatman Polycap GW (Ground Water) capsule filters from Cytiva are specifically designed for sample preparation of ground water samples for dissolved metals analysis. The inline design with stepped hose barbs and hydrophilic polyethersulfone (PES) membrane make it easy to use for field sampling. metals (EPA Method 3NANA5). Specifically designed with field sampling in mind, the Whatman Polycap Ground Water sampling capsule can be used as a convenient inline filter unit. 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.
