- 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 R2A acc. to Ph. Eur., ISO 11133, ready-to-use, sterile, for microbiology
R2A agar is recommended by Ph. Eur. as an alternative medium for testing water samples for the presence of heterotrophic bacteria.
The low nutrient concentration together with the starch and sodium pyruvate content prevent fast-growing bacteria from overgrowing slower-growing or damaged cells. The agar medium is particularly good for counting stressed and damaged bacteria.
