It is essential to validate the sterilization process. Pharmaceutical industries: Remaining bulk of oral medicines ahead of sterilization, drinking water utilized for creating prescription drugs, containers, and surfaces are frequently utilised as samples for bioburden testing in pharmaceutical industries.
