Sterile culture medium plates for the microbiological analysis of liquid samples.

The plates are prepared with our tried and tested dehydrated media mixtures.

The Slanetz-Bartley Agar (Art. No. X935) is recommended by the ISO 7899-2 for enumeration of intestinal streptococci.

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.

Fig.: Example of use of Roti®-Aquatest Plate PCA

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.
