Product details


Sterile ready-to-use culture media plates for microbiological analysis.

  • Diameter 90 mm
  • Surface 63,6 cm2
  • Ready-to-use and sterile
  • Easy to use, reliable detection and simple evaluation
  • Well applicable for microbiological analysis of samples
  • With detailed instructions for use

ROTI®Plate90 are prepared culture media plates with a diameter of 90 mm. They are thus adapted to the size of membrane filters for assaying of low-germ fluids by membrane filtration method. They are also applicable for the microbiological analysis of samples in general.

The germs of expected low-germ liquid samples are concentrated by membrane filtration. Afterwards, the membrane is placed on top of the medium and incubated. Using a membrane with a grid helps counting the resulting colonies.
Our products are tested and approved exclusively for research and development.

Samples which are expected to have a higher microbiological burden are prepared in a serial dilution. Afterwards, every dilution step is plated and incubated. The number of grown colonies is noted as result.

ROTI®Plate90 YE ISO 6222, ISO 11133, ready-to-use, sterile, for microbiology

Yeast extract agar is recommended by the European ISO standard 6222 for testing water samples for the presence of culturable microorganisms and for counting them.

Yeast extract and tryptone are the basic nutrients of this medium. The yeast extract contained is the water-soluble part of the hydrolysed yeast and the source of vitamins, especially of the B group, and growth nutrients that stimulate the development of the microorganisms.
Pancreatically digested casein is a major milk protein and a rich source of nitrogen and amino acids, especially tryptophan, which is valuable for detecting indole production.
