Buffered NaCl Peptone Solution pH 7.0

Diluent for detection and enumeration of microorganisms

according to USP/EP/JP and ISO 21149

Buffered NaCl Peptone Solution pH 7.0 is used for dissolving, suspending and diluting test samples. Its composition conforms to recommendations in the Harmonized Pharmacopoeias for the microbiological examination of non-sterile products. This solution also conforms to ISO 21149 for the detection of viable microorganisms in cosmetics.

Sodium phosphate and potassium phosphate are the buffering agents. Sodium chloride maintains the osmotic balance. A low peptone content provides nitrogen, vitamins, minerals and amino acids to ensure the viability of the organisms. Buffered NaCl Peptone Solution pH 7.0 can be supplemented with tensioactive agents or inactivators of antimicrobial agents, such as polysorbate 80 (ref. 80031).

BufferedNaCl Peptone Solution pH 7.0 is not a culture medium. The minimal nutrient content does not allow significant growth of microorganisms.
