- Easy to use
- Optimal for the membrane filtration method
- Also well applicable for microbiological analysis of samples in general
- Prepared with our proven dehydrated nutrient media mixtures
- With detailed instructions-for-use
ROTI®Aquatest Plates are prepared culture media plates with a diameter of 55 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.
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.
