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.
The absence of endotoxins is mandatory for reproducible, reliable cell culture applications and for many applications in pharmacology and medical research.
Furthermore, all Eppendorf Sterile products fulfill the quality standards defined for our standard consumables. The requirements regarding wetting behavior, liquid tightness, accuracy, chemical resistance, etc. are met in full.
Only those consumables that have passed all the necessary tests shall be labeled “Sterile”, a quality seal which assures customers of the suitability of their Eppendorf consumables for direct use in experiments and analysis without the need for further treatment. Each lot is certified by an external accredited laboratory as a matter of course.
The lot-specific certificates are available on request and on our website.
Sterile consumables are recommended for: Cell culture, applications in microbiology, molecular biology, etc.
