Are the epT.I.P.S. Box / epT.I.P.S. Box 2.0 and the epT.I.P.S. Racks UV-resistant?

The UV stability of epT.I.P.S. box / epT.I.P.S. Box 2.0 (made of polycarbonate) as well as of the epT.I.P.S. racks (made of polypropylene) were tested intensively during development. Boxes and racks were exposed to 254 nm UV light (1 J/cm2) for 16.7 hours. After 10 cycles (167 hours), no signs of adverse effects were detectable. Because the energy of the lamp used is considerably higher than that of a lamp used in a sterile bench, it can be assumed that both boxes can be exposed to UV radiation for at least 300 to 600 hours in a sterile bench without problems. Polypropylene used for epTIPS Racks is three times more resistant against UV radiation than polycarbonate allowing even longer exposure to UV light. If a disinfectant is applied prior to UV irradiation make sure to take off the reagent by wiping off using a cloth soaked in water.

Are Eppendorf products free of RNA?

All products certified with "PCR clean" are tested free of human DNA, DNase, RNase and PCR inhibitors. The following applies from our point of view: Where no human DNA is detected, there can also be no RNA, which is considerably more unstable.

What is the meaning of the PCR Clean seal?

For molecular-biological requirements Eppendorf offers a new standard for uniform purity specifications. All consumables marked with the "Certified PCR Clean” label are guaranteed free of human DNA, DNase, RNase and PCR inhibitors.

How do you make your Biopur products free of pyrogens?

All Biopur products are manufactured fully automatically under cleanroom conditions. This eliminates contamination of the disposables through contact with people. An independent laboratory checks that each individual batch is free of pyrogens.Additionally the products are sterilized by radiation or treatment with ethylene oxide.

What is the shelf life of Eppendorf Biopur products?

If the Biopur products are stored according to the information in the instruction manual they have a shelf life of 5 years. The minimum expiry date is printed on the label of the box.

Why are there double labels on the folding boxes, as "PCR clean" + "Sterile" or "PCR clean" + "Protein-free"?

Due to the modularization of purity grades, some products are labeled with more than one purity grade symbol. For example, the epDualfilter T.I.P.S. has the double seal "PCR clean "+ "Sterile" and the UVette the double seal "PCR clean" + "Protein-free" on the packing. The certification remains unaffected by the modularization.

Are batch-specific certificates for the new purity grades available in the internet?

Yes, the batch-specific purity grades can be downloaded at our certificates homepage .

Can products of the previous and new modular purity grades (with new seals) be used simultaneously in one application?

Yes, if no batch attachment is required for the application, products of the old and new modular purity grades can be used, as their specifications are the same.

What are the reasons for using single-use plasticware in the laboratory?

Contamination and cross-over can only be avoided by using single-use plastic items. In addition, there is no annoying and time-consuming cleaning of glassware.

Are the epTIPS Biopur suitable for safe use in the food industry within Europe?

All Biopur products are manufactured fully automatically under cleanroom conditions. This eliminates contamination of the disposables through contact with people. Beta radiation is used as the sterilization method. An independent laboratory checks that each individual batch is free of pyrogens. The epTIPS Biopur are suitable for use in the food industry according to the Food and Consumer Goods Legislation § 5, paragraph 1 no. 1 (food and consumer goods). Please note: The suitability of a consumer item for the intended purpose, the influence of the filler on taste and smell, and the compliance with limitations (e.g. global migration, specific limitations and other analytical specifications) should be tested by the manufacturer or user for individual cases.

No, the boxes can be autoclaved with the lid closed.

Can the epT.I.P.S. Box / epT.I.P.S. Box 2.0 be autoclaved at 133 °C?

No, the epT.I.P.S. Box / epT.I.P.S. Box 2.0 cannot be autoclaved at 133 °C. We recommend 121 °C.

Is the epT.I.P.S. Box 2.0 compatible with the Reloads for the forerunner epT.I.P.S. Box?

Yes, the epT.I.P.S. ® Box 2.0 is compatible with all epT.I.P.S. Reloads and all epT.I.P.S. BioBased Reloads.

What is the difference between epT.I.P.S. Box / epT.I.P.S. Box 2.0 and epT.I.P.S. Rack?

The epT.I.P.S. ® Box 2.0 in the new design, equipped with additional benefits, is the successor product of the epT.I.P.S. ® Box used in the market since 2002. Like its predecessor, the epT.I.P.S. Box 2.0 can be autoclaved up to 100 times and can be filled with all epT.I.P.S. Reload variants for pipette tips in Eppendorf Quality, PCR clean, Biopur ® and PCR clean/Sterile.
