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.
In the box, each 5 plates are packaged in a blister in discrete compartments. Thus, the sterile plates can be obtained individually.
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.
Expiration time on request.
Do NOT freeze!
