Maximum Recovery Diluent (Tryptone Salt Broth) is used as an isotonic diluent for maximum recovery of microorganisms and is not intended for use in the diagnosis of disease or other conditions in humans. An osmotically controlled solution which is an alternative to, and a replacement for, 1/4 strength Ringer’s Tablets (NCM0191K). The presence of a low level of peptone lessens the physiological shock normally experienced by bacterial cells when they are introduced to a diluent such as Ringer’s Solution. The level of peptone is such that multiplication of the organisms is not possible in the time in which the sample will be present in the diluent (1 - 2 hours). This formula is recommended by ISO 6887-1:2017.
