颇尔 Kleenpak capsule filters with intrinsically hydrophilic positive zeta potential Posidyne membrane are rugged, self-contained sanitary filters designed for small-batch sterile filtration of aqueous pharmaceutical solutions.With a net positive charge in most aqueous solutions from pH 3 to 10, Kleenpak Capsules with Posidyne Membrane Assemblies can be effective in removing contaminants such as cell debris and endotoxin smaller than the filter rating.


  • Positive Zeta potential for enhanced efficiency in aqueous solutions
  • Double-layer sterilizing membranes for high reliability
  • 100% integrity and pressure-tested
  • High protein recovery from serum and most protein solutions
  • 0.2 µm NF grade for sterilization
  • 0.1 µm NT grade for diminutive bacteria and mycoplasma removal
  • Low filter extractables
  • Sanitary vent and drain valves with non-twist hose barbs
  • Upstream hold-up volumes (< 1 mL)
  • Repeatedly autoclavable
  • Manufactured for use in conformance with cGMP
  • IS0 9000 Certified Quality System
  • Pharmaceutical P optimized
  • Certificate of Test provided

Quality and Bio-Safety Biological Tests

  • Meets USP Biological Reactivity Test, in vivo, for Class VI-121 °C Plastics

Effluent Quality Tests*

  • Meets Cleanliness per USP Particulates in Injectables
  • Non-Fiber-Releasing
  • Non-Pyrogenic per USP Bacterial
  • Endotoxins (< 0.25 EU/mL)
  • Meets Total Organic Carbon and Water Conductivity per USP Purified Water; pH per Sterile Purified Water

 * Per lot sample soak or rinse-up flush aliquots.
