Sartorius Nongridded Sterile Cellulose Membrane Filters PROMO

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: 0.2 μm, 0.45 μm, 0.65 μm, 0.8 μm, 1.2 μm, 3.0 μm and 8.0 μm 8 μm filters are used as prefilters in a prefilter attachment
• They retain coarse particles, while allowing microorganisms through for recovery on a bacteria-retentive filter 0.2 μm filters are the standard for sterile filtration and are validated by the Bacteria Challenge Test (BCT) 0.45 μm filters are manufactured according to ISO 7704 White, un-gridded filters in 47 or 50 mm (1.9 or 2 in.) diameter sizes
