Cytiva Whatman - Model Polycap AS -Nylon Membrane Filter and Glass Microfiber (GMF) Prefilter
Cytiva’s Whatman Polycap AS (Aqueous Solution) combines a nylon membrane filter and glass microfiber (GMF) prefilter for a long lifetime device that can filter large volumes of even difficult, particulate-laden samples.
Cytiva’s Whatman Polycap AS (Aqueous Solution) combines a nylon membrane filter and glass microfiber (GMF) prefilter for a long lifetime device that can filter large volumes of even difficult, particulate-laden samples.
- 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
Whatman capsule filters from Cytiva Healthcare’s Life Sciences business are available for a variety of applications. Browse the Polycap line to find the filter that matches your needs.
