The frequency of sampling will depend upon the criticality of specified web-sites and the subsequent cure been given via the solution right after it's been aseptically processed. Table 2 demonstrates advised frequencies of sampling in reducing buy of frequency of sampling and in relation towards the criticality of the realm of your controlled setting being sampled. Table 2. Suggested Frequency of Sampling on the Basis of Criticality of Controlled Natural environment
