Purity Grades

Eppendorf purity grades for tips, tubes and plates

*The suffix "-free" in connection with the purity classes mean that the test showed conformity within the detection limits (see lot-specific certificate). Learn more

Eppendorf consumables stand for the highest quality and purity. This is achieved by the following:

  • Manufacturing using the purest raw materials
  • Fully automatic production in clean room conditions
  • Quality and functional checks of all lots
  • Continuous quality assurance throughout the entire production process – from the initial material to the finished product

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: Eppendorf Quality as well as more advanced purity grades: Sterile, Protein-free*, PCR clean and Biopur. In addition to our internal process controls, products with the purity grades Sterile, Protein-free, PCR clean or Biopur are certified 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 make the inspection certificate for each delivered lot available online.

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 epQuality™ Consumables 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.
