Hydrofil™ HT

Nylon 6.6 Membrane Cartridge Filters

A range of microbially rated cartridge filters from Porvair Filtration Group, featuring the latest developments in membrane technology, HydrofilTM HT cartridges are based on a naturally hydrophilic nylon membrane. When combined with quality all – polypropylene cartridge components and high integrity manufacturing techniques common to all Porvair cartridge filters, the nylon membrane provides a high strength, long life cartridge of consistently precise particle retention across a wide range of particle sizes.

Features and Benefits

  • Guaranteed microbial ratings
    Hydrofil™ HT cartridges are validated for bacterial removal according to HIMA guidelines and ASTM F838-05, with a log reduction value >7. They are therefore suitable for applications requiring sterilising grade filtration.
  • Excellent chemical compatibility
  • Cartridge integrity and low TOC levels
    Each Hydrofil™ HT HT module of every cartridge is individually integrity tested. Each complete filter cartridge is flushed with pure water which is inspected daily for pyrogens using the standard LAL test. When required, they can be pulse flushed with 18MΩ.cm pyrogen-free ultra-clean water.
  • Suitable for steam sterilising
  • Full traceability

Applications

  • Biopharmaceuticals
    For the sub-micronic filtration of ingredients, intermediates, make-up waters and final products, including sterilisation, clarification and bioburden reduction.
  • Electronics and semiconductors
    For the sub-micronic filtration of process water and chemicals, including solvents, developers and photoresists. Applications typically include central water plant treatment and critical ‘wet bench’ point of use filtration.
  • Fine chemicals
  • Beverages
  • Pure water supply
