These Polycap™ AS (aqueous solutions) capsule filters combine a glass microfiber (GMF) prefilter over a nylon membrane final filter to provide maximum filtration of difficult, particulate-laden solutions.

• First layer (GMF) acts as a prefilter to ensure longer membrane life and higher filtration efficiency
• Nylon membrane filter layer is inherently hydrophilic, has low extractables, is biosafe, and has excellent flow rates
• PP housing is thermally fused (no glues, adhesives, or extraneous materials), reducing extractable levels
• Can be tested with bubble point, pressure decay, or forward flow methods
• Available in presterilised and non sterile (autoclavable) versions

Polycap™ AS are capsule filters specifically designed for high-volume filtration of aqueous sample solutions in a compact size.
