Maximum Recovery Diluent (Peptone Saline Diluent)

Maximum Recovery Diluent (Peptone Saline Diluent) is used as an isotonic diluent for maximum recovery of microorganisms in a laboratory setting. Maximum Recovery Diluent (Peptone Saline Diluent) is not intended for use in the diagnosis of disease or other conditions in humans.

Maximum Recovery Diluent provides the nutritious properties of peptone with the osmotic support of physiological saline. The low peptone concentration in the diluent at a pH of 7.0 ± 0.2 reduces organism multiplication in the sample for at least one hour during the dilution stage. The isotonic strength of the diluent ensures recovery and minimizes physiological shock normally experienced by microorganisms upon inoculation. The presence of peptone in Maximum Recovery Diluent provides viable counts to ensure accurate quantitative procedures are performed.
