Whatman™ Polydisc SPF disc filters from Cytiva contain a glass microfiber (GMF) and polyethersulfone (PES) stack designed to purify serum and other hard-to-filter solutions.
High-throughput, in-line prefilters for use upstream of serum filters
GMF prefilter captures large particles and cell debris while PES stack removes remaining particles and bacteria larger than 1 µm
Designed to extend the life of downstream serum filters
Effective for microbiology and tissue culture, immunoassays, virology, and diagnostic controls
6 to 10 mm i.d. hose connection
Disc filters for serum prefiltration
Filtering serum requires removing proteins, lipids, salts, and other cell debris. This range of particulate matter is effectively handled with multi-layer prefilters to facilitate downstream work and to avoid clogging later serum filters.
Polydisc SPF stacks a high-flow, hydrophilic PES membrane with a high particle-loading GMF filter to clean out particulates from serum and reduce stress on the final-stage serum filters.
