HPPS Filters

For bacteria removal in aqueous liquids with high particle loads.

Applications
  • Cell culture media
  • Sera/plasma
  • Vaccines
  • Diagnostics
  • Buffers
  • Biologicals
  • Ophthalmics
Features and Benefits

PES Dual LayerHPPS is a family of pharmaceutical grade, Polyethersulfone (PES) sterilizing filters. This dual layer filter has an integrated, high capacity prefilter and an asymmetric PES final filter.  

  • 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
  • Integrated prefilter saves space by eliminating separate prefilter/housing
  • Prefilter extends the life of the final filter
  • Common pore size combinations: 0.2/0.1, 0.5/0.2, 0.8/0.2 microns

Validation

HPPS filters are validated 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 challenge level is a minimum of 107 organisms per cm2 of filter media. CPF filters have > 7-log removal when challenged with the organisms listed below (0.03μm, 0.10μm and 0.22μm meet the FDA definition of sterilizing grade filters). Validation Guides are available upon request.

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

HPPS filters are 100% integrity tested. CPF filters are developed and manufactured under an ISO 9001:2015 certified Quality Management System and designed to be used in cGMP-compliant processes. 

HPPS Cartridges 

Available from 5-40 inches in length with several end connections and O-ring options.  For applications using elevated temperatures,  HPPS/HT Cartridges can be used in processes up to 203°F.
