Description

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
