Roti®-Aquatest Plate Staph.Ph.Eur.
Ph.Eur., ready-to-use, sterile, for microbiology
For isolation of pathogenic staphylococci.
Sterile culture medium plates for the microbiological analysis of liquid samples.
The plates are prepared with our tried and tested dehydrated media mixtures.
The Mannitol Salt Agar (Chapman Agar) (Art. No. CL81) is recommended by the Ph.Eur. for isolation of pathogenic staphylococci.
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.
