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

  • 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
