Moist heat destroys microorganisms because of the irreversible coagulation and denaturation of enzymes and structural proteins.
Chemical indicators are made use of to observe if the parameters to obtain sterilization happen to be met for a selected sterilization approach.
In chemistry, chemical indicators are substances that endure a distinct observable improve when exposed to sure problems, generally connected with the existence of acids or bases. The most typical change can be a coloration shift, but olfactory indicators, which react by altering scent, are also utilised.
Interpretation: Exact interpretation requires suitable training and understanding of the specific indicator's qualities. Misinterpretation can cause Bogus positives or negatives.
