Capsule Filter, Polycap GW 75, PES, 0.45 µm

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
