ROTI^®Plate90 Sab4Cla

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 with chloramphenicol is recommended by Ph. Eur. and USP for testing for the presence of fungi by the membrane filter method, and for counting fungal colonies on agar plates or by the dilution method (MPN method).

This agar has a lower concentration of chloramphenicol than 1AX0, making it less inhibitory to contaminant bacteria.
