Diluting Fluid A is applied given that the dilution medium with out exposing the filter on the product or service. Right after addition from the very low-amount inoculum to the ultimate rinse, the filter is plated as above. Method-unique loss of microorganisms can be estimated by comparing the Restoration within the diluting Fluid A group for the inoculum rely.
