Eppendorf consumables with the purity grade Sterile are sterilized by irradiation or ethylene oxide gassing in accordance with ISO 11137 or ISO 11135 with a Sterility Assurance Level (SAL) of 10-6. For each lot of sterile products a lot-specific certificate is provided. The testing procedures for sterility testing comply with the requirements of Ph. Eur. 2.6.12 (European Pharmacopeia) and USP (United States Pharmacopeia).
Sterility describes an aseptic condition, meaning the absence of* living organisms. During sterilization transmissible agents like fungi, bacteria, or viruses, that can affect e.g. cell culture, food but also standard reactions in molecular biology, are effectively eliminated.
In addition each lot is tested for the absence of endotoxins in accordance with Ph. Eur. 2.6.14, and thus demonstrated as being free of* pyrogens.
