Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters: 0.45μm

Description

• Ensure quality control in microbiological filtering
• Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.45μm are single-packed membranes with colored grids for colony counting, particle testing and microscopy
• The 0.45μm pore size is made in accordance with ISO 7704
• Choose from two diameters and quantities in a range of filter/grid color combinations
• 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 Manufactured in accordance with ISO 7704, ISO 7899-2, ISO 8199, ISO 9308-1 and EN 12780 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 Cellulose Nitrate membranes Defined particle retention and outstanding, reliable recovery rates for microorganisms Cellulose nitrate filters (mixed cellulose ester) combine high flow rates with optimal colony growth The various-colored grids divide the filtration area into squares and provide the best possible color contrast Enables easy and reliable counting and identification of colonies and particles Does not influence the growth of bacteria and micro-colonies 0.45μm filters are manufactured in accordance with ISO 7704 standards Available in 47 and 50mm (1.9 or 2.0 in.) diameters
