Our Sterility Testing Services
Sterility testing is carried out by our team of microbiological experts to verify the effectiveness of a sterilization process using ISO11137, ISO11135 or aseptic manufacture
STERIS completes sterility testing to either USP/EP or ISO 11737 using membrane filtration, direct immersion (inoculation) or removal of microorganisms from the product. These techniques can be applied on the total product part of the product or of the fluid pathway. The necessary techniques depend on product characteristics and Customer requirements.
Sterility testing
Sterility testing is performed for three reasons:
- Test for sterility (USP/EP)- Confirm requirements for sterility of a product following exposure to a sterilization process or aseptic manufacture
- Test of sterility (ISO11737-2)- Qualify the minimum irradiation dose needed to achieve a specified sterility assurance level (SAL)
- Test for Sterility of Sub-lethal EO validation samples (ISO11135) to establish and prove the relationship between the BI and the natural product bioburden.
