Microporous membrane


Microporous membrane is an indispensable consumable for pharmaceutical microbial test and some small-scale liquid filtration.Our company now offers a variety of materials. Different diameters and pore microporous membrane can be used with F47 Microbial Enumeration Funnel or FC50A/FC50B Reusable Membrane Filter to do microbial enumeration test; also be used to liquid particulate removal and bio-burden reduction or even sterilization filter (0.22μm).


  • Reliable quality and stable aperture;
  • Can withstand 121 ℃, 30min moist heat sterilization;
  • With independent non-aseptic packaging and aseptic packaging (0.22μm only non-aseptic packaging) for customers’ choice;
  • Strong hydrophilicity, microbial enumeration tester’s membrane recovery ratio meets the current pharmacopoeia requirement.

Technical Parameters
