ROTI®Plaque90 Sab4

Sterile ready-to-use culture media plates for microbiological analysis.

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.

Sabouraud 4 % Glucose Agar (Sab4) is recommended for the cultivation and maintenance of pathogenic and saprophytic fungi, or of yeasts like Candida albicans. It is a medium which has been widely used for the isolation of fungi and in general work in mycology.
Sabouraud 4 % Glucose Agar is recommended by the Pharmacopeia Europaea for sample examination by the membrane-filter method for the presence of fungi. Furthermore, it is recommended for counting of fungal colonies on agar plates or by dilution series (MPN method).
