Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters: 0.2μm

Description

Ensure quality control in routine microbiological filtering. Sartorius Gridded Sterile Cellulose Nitrate Membrane Filters, 0.2μm are single-packed membranes with black grids for colony counting, particle testing and microscopy. The 0.2μm pore size is BCT validated. Choose from two diameters and packaging quantities.

Sterile, individually packaged filters for strict quality control

• Pre-sterilized via gamma irradiation at 25kGray
• Ready-to-use to save preparatory time

  • 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
• Black grid divides the filtration area in 130 squares and provides stark color contrast
  • Enables easy and reliable counting and identification of colonies and particles
  • Does not influence the growth of bacteria and micro-colonies
• 0.2μm filters are the standard for sterile filtration and are validated by the Bacteria Challenge Test (BCT)
• Available in 47 and 50mm (1.9 and 2.0 in,) diameters
