Eppendorf purity grades for tips, tubes and plates

Eppendorf Quality

The “Eppendorf Quality” fulfill everything expected of reliable, easy-to-handle consumables. With the aid of high-quality base material and permanent checks during production, Eppendorf consumables in "Eppendorf Quality" are ideal for many tasks in the lab.

Sterile

Eppendorf consumables with the purity grade “Sterile” are sterilized by irradiation according to ISO 11137 or ^{by ethylene oxide according to} ISO 11135 with a Sterility Assurance Level(SAL) of 10^-6 . Lot-specific certificates document sterility and the absence of endotoxins in accordance with Ph. Eur. 2.6.14.

PCR clean

All Eppendorf consumables with the purity grade “PCR clean” are DNase and RNase-free, and free of PCR inhibitors. It is also guaranteed that the consumables are free of contaminating human DNA.

PCR clean + Sterile

The purity level "PCR clean + Sterile" certifies the criteria of the purity level "PCR clean" and “Sterile”. For further details please read the respective purity grades.

Forensic DNA Grade

The demanding requirements of the ISO 18385 are fulfilled by “Eppendorf Forensic DNA Grade“ consumables. These products help to further minimize the risk of human DNA contamination in forensic DNA analysis. Individually blistered packaging or “mini batches” in re-sealable bags also help to protect against contamination.

Eppendorf Biopur

Consumables available in this highest possible degree of Eppendorf purity grades are guaranteed to be sterile and free of pyrogens, RNases, DNases, DNA and ATP as well as PCR inhibitors. Individually blistered packaging provides effective protection against soiling and contamination.

PCR clean + Protein-free

The purity level "PCR clean + Protein-free" certifies the criteria of the purity level "PCR clean" and and is in addition protein-free and thus free of unspecific signals or reactions due toprotein contamination.

With the strictest control criteria, internally and externally monitored, we guarantee the consistently high quality of our products – lot by lot.

Our consumables are available in a variety of purity grades. In addition to our internal process controls, products with the purity grades Sterile, Protein-free, PCR clean, Forensic Grade or Biopur are tested for biological contamination by an accredited external lab. This allows us to ensure we consistently meet our customer‘s high demands when it comes to the high quality and purity of our products. As a special service, we provide the corresponding lot-specific certificate of analysis (CoA) online for each batch delivered.

The shelf life can only be guaranteed for sealed and adequately stored items. The storage conditions can also be found in the operating instructions in the section "Technical data".

The exact expiry date is indicated on the product label in the following format: YYYY-MM-DD, where the exact expiry date is always the 28th of the month. This format follows FDA recommendations for the Unique Device Identification (UDI) system.

The shelf life of 8 years of our consumables in "Eppendorf Quality" relates to the technical material properties of our products. The limited shelf life of 5 years for the higher purity grades (e.g., sterility) refers to the products’ purity, as it may be more strongly influenced by packaging and storage conditions than the material properties.
