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.
Columbia Agar is recommended by the Ph. Eur. and USP for subculturing of samples enumeration and semiquantitative detection of clostridiae. It is a highly nutritive general purpose medium for the cultivation of fastidious organisms.
The contained peptone provides nitrogen, vitamins, minerals and amino acids that are important for growth while sodium chloride maintains the osmotic balance. Corn starch neutralises toxic fatty acids that may be present in the agar.
