Gridded Membranes

C/N micro filter discs Sartorius Biotechnology cellulose nitrate 47mm gridded membranes are used for the quantitative determination of microorganisms present in a liquid sample. The quantity can represent either the total bioburden, e.g., all bacteria, yeast and moulds, or the detection and quantification of a particular species of product-specific microorganisms. With a pore size of 0.45ľm, these microbiology QA/QC gridded membranes come in a variety of colours to make counting quick and easy.

Pre-sterililized and ready-to-use, these gridded membranes save preparatory time

Identification and lot number printed on each individual envelope

Conform to GLP and market regulatory standards for laboratory filtration

For busy micro-labs with high daily through-puts we recommend the new ‘e.motion’ dispensor with membrane tapes.

Microbiological Nutrient Pad Sets

Nutrient pad sets – dehydrated media pads in petri dishes , pre-sterilized, along with suitable membrane filters for economical, time-saving microbiological quality control. No other ready-to-use culture media assures such consistently high quality and reproducible results up to 24 months.

Microsart E.Motion Dispensers

Efficient and ergonomic workflows for reliable and fast membrane filter dispensing. Thanks to the small footprint the Microsart e.motion dispenser saves precious space under the laminar air flow which can be used for samples, media and funnels instead. The Microsart e.motion dispenser offers the easiest and most flexible way of membrane filter dispensing.

You have the freedom of choice between 3 different operation modes.

Choose what is most convenient for you:

  • push-button
  • foot-switch or
  • sensor mode

Efficient Workflow

The new Big Packs containing 250 membrane filters enable you to work a complete shift without the need to stop and reload the Microsart® e.motion dispenser.

The dispenser’s low weight and convenient handle makes it easy to remove or transport.

The membrane filter band specially designed for the Microsart® e.motion dispenser can be conveniently inserted, and changed quickly as needed.

A window in the field of dispensing makes the information on the membrane filter band such as lot number, membrane filter type and the quantity of filters left visible! For better scheduling of tests and easy traceability.


Microbiological Quality Control of liquid samples:

  • Beverages (beer, wine, softdrinks, bottled water)
  • Cosmetics
  • Pharmaceutical Analysis
  • (WFI, purified water, microbial limits testing of non-sterile products, bioburden testing)
  • Environmental Analysis (Water monitoring)
