Sterile Membrane Filters

Sterile, gridded membrane filters are widely used for routine microbiological quality control due to the benefits they offer. Whether single-packed or dispenser-ready, the membrane filters are ready-to-use and each filter is individually packed, offering highest security whilst saving preparatory time. Each individual envelope is marked with the filter identification and lot number.

The membrane filters are available in different pore sizes and three different material types. Cellulose nitrate filters (mixed cellulose ester) contain a mixture of cellulose nitrate and cellulose acetate, a material which assures effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal stability with very low adsorption characteristics. The various filter colors allow the best possible contrast to the colonies for easy and reliable quantification and identification.

  • Outstanding recovery rates for microorganisms
  • 0.45 µm filters acc. to ISO 7704
  • High flow membranes available
  • Three different colors
  • Various pore sizes
  • Certified quality
  • Gamma irradiated at 25 kGray
  • The membrane filters are in accordance with the following norms: ISO 7704, ISO 7899-2, ISO 8199, ISO 9308-1 and EN 12780.

Microsart® e.motion Membrane Filters

The Microsart® e.motion membrane filters are suitable for the use with the Microsart® e.motion dispenser. The filters are individually sterile-sealed on a band without any protective paper. The special pleating as well as the shape of the sealing of the band of membrane filters ensures a perfectly flat and uniform dispensing of the individual membrane filters.

The Microsart® e.motion membrane filters are also ideal for all users of the Sartorius Nutrient Pad Sets: most of the NPS types are available with Microsart® e.motion membrane filters.

  • Outstanding recovery rates for microorganisms
  • 0.45 µm are acc. to ISO 7704
  • Multi-fit: Fits into other dispensers
  • Protective paper-free
  • Packaged on a special pleated band
  • Product data is printed on individual envelopes
  • High flow membranes
  • Gamma irradiated, 25 kGray

Non-Sterile Membrane Filters

Non-sterile, gridded membrane filters can be used for colony counting, particle testing and microscopy. Before usage, the filters first need to be sterilized (e.g. by autoclaving at 121°C). The membrane filters are available in different pore sizes and three different material types. Cellulose nitrate filters (mixed cellulose ester) contain a mixture of cellulose nitrate and cellulose acetate, which assures effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal stability with very low adsorption characteristics. The various filter colors allow the best possible contrast to the colonies or particles for easy and reliable quantification and identification.

  • High flow membranes
  • Three different colors
  • The membrane filters are in accordance with the following norms: ISO 7704, ISO 7899-2, ISO 8199, ISO 9308-1 and EN 12780.
 

Microsart e.motion Dispenser

Microsart™ e.motion Dispenser – membrane filters on demand. The completely new membrane filter dispenser meets all requirements placed on advanced laboratory equipment. The membrane filters are released from their sterile packaging fully automatically at the touch of a button or hands-free – a dispensing operation is triggered when the optical sensor detects approaching tweezers.
