    PRAS Dilution Blanks are ideal for serial dilutions prior to plating for culture recovery or for preparing dilutions for viable organism counts.

    PRAS Dilution blanks

    PRAS Dilution blanks

    Dilution Blanks are a buffered mineral salt solution with sodium thioglycollate and L-cysteine added to provide a reduced environment.

    This formulation has been prepared to provide an environment which maintains the viability of most microorganisms without significant multiplication. Dilution Blanks have been designed to meet the stringent viability requirements of obligate anaerobes. This medium is prepared, dispensed, and packaged under oxygen-free conditions to prevent the formation of oxidized products prior to use.
