Sterility Testing Methods
There are two primary ways to perform sterility testing: the membrane filtration sterility method and direct inoculation. We use the proper methodology based on your products and the appropriate compendia.
Membrane Filtration Sterility Testing
- Samples are passed through filter with aseptic techniques/processes
- Most commonly used method per USP 71 for many products
- Samples with antimicrobial properties are neutralized to ensure accuracy
Direct Inoculation Sterility Testing
- Sample is directly introduced with aseptic techniques/processes
- Commonly used on non-filterable products (oils, suspensions, bulk solids, etc.) per USP 71
- Samples with antimicrobial properties are neutralized to ensure accuracy
Our Processes Help Speed Turnaround Times (TAT)
We continually work to automate our sterility testing process to remove variability and the potential for contamination, which not only increases accuracy but helps speed turnaround times.
