Whatman™ Polycap AS, 36 capsule filter, sterile, 0.2 µm, SB inlet and outlet, plus filling bell

Overview
Whatman™ Polycap AS (aqueous solutions) capsule filters from Cytiva 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 (0.2, 0.45, and 1.0 µm) life and higher filtration efficiency.
Nylon membrane filter layer is inherently hydrophilic, has low extractables, is biosafe, and has excellent flow rates
Polypropylene 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 presterilized and nonsterile (autoclavable) versions
Manufactured according to ISO9001:2008 QMS standards
Polycap AS for aqueous solutions
Polycap AS are Whatman™ capsule filters specifically designed for high-volume filtration of aqueous sample solutions in a compact size. With a nylon membrane filter and GMF prefilter, these filters have a long usable life.
