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.
