Description
LPT Dilution Broth Base is a diluting and neutralising medium for preparing cosmetic samples for microbiological examination.
Histidine, lecithin and polysorbate neutralise preservative activity that could otherwise suppress viable microorganisms during sample preparation. Peptone supplies nutrients while the phosphate system buffers the suspension.
A cosmetic sample is homogenised in the prepared broth and decimal dilutions are produced for subsequent inoculation onto the required recovery or enumeration media.
