    Sterile, individually packaged filters for strict quality control

    • Pre-sterilized via gamma irradiation at 25kGray
    • Ready-to-use to save preparatory time
    • Avoids contamination of remaining filters in opened packs
    • Filter identification and lot number are printed on each individual envelope
    • Each membrane is checked to ensure:
      • It is not damaged in any way
      • It is positioned correctly with no slippage under the edge seal
      • It is free of particles
      • Each envelope has readable lettering
    High-quality membranes for a variety of lab applications
    • Defined particle retention and outstanding, reliable recovery rates for microorganisms
    • Choice of two membrane materials:
      • Cellulose nitrate filters (mixed cellulose ester) assure effective retention combined with high flow rates and optimal colony growth
      • Cellulose acetate filters combine high flow rates and thermal stability with very low adsorption characteristics
    • Available in 7 different pore sizes: 0.2µm, 0.45µm, 0.65µm, 0.8µm, 1.2µm, 3.0µm and 8.0µm
      • 8µm filters are used as prefilters in a prefilter attachment. They retain coarse particles, while allowing microorganisms through for recovery on a bacteria-retentive filter
      • 0.2µm filters are the standard for sterile filtration and are validated by the Bacteria Challenge Test (BCT)
      • 0.45µm filters are manufactured according to ISO 7704
    • White, un-gridded filters in 47 or 50mm (1.9 or 2 in.) diameter sizes
