In preparing media via the formulas established forth herein, dissolve the soluble solids in the water, making use of warmth, if needed, to result total Remedy, and add answers of hydrochloric acid or sodium hydroxide in quantities enough to produce the desired pH inside the medium when it is ready to be used. Decide the pH at 25 ± two
For drug commodities, both protection and efficiency are important. Within the a single hand, drug security is decided by whether the get more info chemical composition and content with the drug are Risk-free, and Alternatively, drug safety is decided by whether the drug is contaminated by microorganisms.
