General description

Whatman Polycap SPF capsule filters from Cytiva are optimized for prefiltration applications. They are typically used upstream of a Polycap AS or Polycap TC capsule during enzyme, nutrient media or buffer filtration.

Capsule filters for serum filtration

Biological filtration, especially serum filtration, is often difficult because of the high concentration of complex particulates, lipids, triglycerides, and lipoproteins in solution that can clog filters. Single-layer membrane filters clog rapidly without proper prefiltration.

Polycap SPF prefilters are highly suitable for biological filtration, especially serum, buffer, and enzyme filtration, because of the density graded pre-filtration layers they contain. Prefiltration with Whatman Polycap SPF can help extend the life of the final filter.

Application

Biologicals, Buffers, Diagnostic standards, Enzymes, Immunologicals, Nutrients, Serum prefiltration, Tissue culture media, Viral suspensions.

Features and Benefits

  • Three layers of filter media: fine glass microfiber (GMF), ultrafine GMF, and polyethersulfone (PES)
  • Suitable for hard-to-filter solutions, particularly sera and protein solutions
  • Can be sterilized by autoclaving
  • Manufactured according to ISO9001:2008 QMS standards
  • Well suited for serum, viral suspension, nutrient, biological, immunological, enzyme, and buffer filtration
