Direct Inoculation Method
Although international pharmacopoeias recommend using standard membrane filtration for sterility testing, there are certain products that are not filterable or deformable. These products are normally tested using direct inoculation. In this method, the test sample is added directly into the required media, ensuring that the amount of sample is below 10% of the total media volume.
To comply with your different direct inoculation method requirements, we offer sterility test media in various volumes, from 9 mL tubes up to 750 mL bottles.
