MEMBRANE FILTER CARTRIDGES
Membrane filter cartridges are used as a final filtration step for sterile or high efficiency filtration of liquids and gases. STERIPleat Series membrane cartridges by Siga Filtration are manufactured in clean room environment and are fully traceable with batch and individual serial number. Hard outer cage protects the pleats from damage and protects the membrane during installation, cleaning, sanitisation.

All STERIPleat membrane filter cartridges are manufactured from FDA approved components and suitable for food contact.

STERIPleat Nylon pleated membrane filter cartridges feature a hydrophilic Nylon 6,6 membrane and Polypropylene hardware. Suitable for sterile 0.2 micron filtration.  Validated for bacterial removal according to HIMA guidelines and ASTM F838-05.

STERIPleat PES pleated membrane filter cartridges come with a hydrophilic PES membrane and Polypropylene hardware. Suitable for 0.2 micron filtration of water. Also used for sterile filtration of beer at 0.45 micron. Validated for bacterial removal according to HIMA guidelines and ASTM F838-05.

STERIPleat Bev filter cartridges have been specially designed for sterile filtration of beer and other beverages down to 0.45 micron. All components meet or exceed requirements for food contact. Validated for bacterial removal according to HIMA guidelines and ASTM F838-05.

STERIPleat PTFE pleated membrane filter cartridges come with hydrophobic membranes for sterile or high purity filtration of gases, chemicals and solvents. Validated for bacterial removal according to PDA, HIMA guidelines & ASTM F838-05.

STERIPleat Vent pleated membrane filter cartridges feature a hydrophobic membrane for vent filtration. These filters provide high flow rates at low clean differential pressure making them ideal for venting applications. Validated for bacterial removal according to PDA, HIMA guidelines & ASTM F838-05.

  • STERIPleat Vent – Sterilising Grade Filter Cartridge for Air/Gases

    The enhanced Hydrophobic PTFE membrane offers exceptionally high gas flow rates at low pressure differentials. STERIPleat Vent cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the PTFE membrane make the STERIPleat Vent filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed.

  • STERIPleat Nylon Membrane Filter Cartridge

    STERIPleat Nylon cartridges are based on a naturally hydrophilic nylon membrane. When combined with quality all-polypropylene cartridge components and high integrity manufacturing techniques, the nylon membrane provides a high strength, long life cartridge of consistently precise particle retention across a wide range of particle sizes. STERIPleat Nylon cartridges benefit from high protein binding characteristics of nylon membranes. They are also highly resistant to integrity failure caused by steam sterilisation.
