Biopharmaceutical Grade
BPVWL Cartridge Filters
High Capacity PVDF Membrane
Biopharmaceutical grade PVWL filters are made using hydrophilic
polyvinylidene fluoride (PVDF) membrane. The proprietary
membrane casting process creates a thick membrane with
excellent retention characteristics and flow rates and low protein
binding. BPVWL cartridges are used for a wide range of critical
applications in the biopharmaceutical production.
Applications include bioburden reduction in buffers and media,
water for injection (WFI), solvents, alcohols and other liquids. Our
filters provide high efficiency, validatable performance protecting
sterilizing grade filters.
PVDF is particularly suited for the filtration of products containing
elements that can adsorb to the media, such as preservatives and
proteins. The very low binding nature of PVDF makes it a good
choice for filtration of valuable protein solutions such as vaccines,
plasma products, MAb products, other biopharmaceuticals as
well as products that contain low amounts of preservatives
