Cytiva Whatman Polycap AS (aqueous solutions) capsule filters from Cytiva combines a glass microfiber (GMF) prefilter over a nylon membrane final filter to provide maximum filtration of difficult, particulate-laden solutions.
Whatman Polycap AS (aqueous solutions) capsule filters from Cytiva combines 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
Recyclable after use. Learn how you can recycle it.
