BPS Bioburden Control Filters

For the prevention of bioburden contamination and to reduce microbials when sterilization is not required.

Applications
  • Diagnostics
  • SVPs & LVPs
  • Water for Injection
  • Water Purification
  • Buffers
  • Sera/plasma
  • Vaccines
  • Ophthalmics
Features and Benefits

PES Dual LayerBPS is a family of biological grade, single and dual layer Polyethersulfone (PES) filters. They are designed with a single Asymmetric PES membrane and have the option of adding a High Capacity PES prefilter layer.

  • Delivers high flow across a wide pH range
  • Low binding characteristics (much lower than cellulose acetate and nylon) for filtering liquids with preservatives and proteins that can adsorb to media
  • Optional integrated prefilter saves space by eliminating separate prefilter and housing
  • Prefilter extends the life of the final filter

Validation

BPS filters are validated for bioburden control using test procedures that comply with ASTM F 838-15(ae1) protocols for the determination of bacterial retention in filters used for liquid filtration. The filters are challenged with the organisms listed below.

  • 0.03μm: Acholeplasma laidlawii 
  • 0.10μm: Brevundimonas diminuta
  • 0.22μm: Brevundimonas diminuta
  • 0.45μm: Serratia marcescens
  • 0.65μm: Saccharomyces cerevisiae

Validation Guides are available upon request.
