Whatman Polycap AS

Polycap™ AS (Aqueous Solution) is a unique product recommended for filtering aqueous solutions. It combines a glass microfiber (GMF) prefilter and a nylon membrane, prolonging the life of the filter and allowing larger volumes and difficult samples to be filtered easily.

Features and benefits

• First layer (GMF) acts as a prefilter to ensure longer membrane (0.2, 0.45 and 1.0 µm) life and higher filtration efficiency
• Nylon membrane layer is inherently hydrophilic, has low extractables, is biosafe and has excellent flow rates
• Ultra-clean containing no surfactant or mold release agents
• Housing thermally fused (no glues, adhesives or extraneous materials)
• Integrity-testable by bubble point, pressure decay or forward flow methods
• Provides highly effective filtration area in a small size Autoclavable; some presterilized with gamma irradiation
• Manufactured in clean room facilities under ISO Quality Systems
