Do Eppendorf Safe-Lock Tubes Biobased differ in any aspect from their standard counterparts?

No, Eppendorf Safe-Lock Tubes Biobased are functionally equivalent to their counterparts made of standard material. They exhibit identical performance across all key parameters, including centrifugation stability, lid tightness, and chemical resistance. The tubes are manufactured to the same high purity standards and demonstrate equal assay performance. Testing across typical molecular and cell biology workflows — such as bacterial culture, sample storage, and PCR — confirmed no differences in functionality. Furthermore, the Biobased version maintains the same low levels of leachables, ensuring consistent sample integrity.

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.

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 lot specific certificates for the purity grades available in the internet?

Yes, the lot specific purity certificates, so-called Test report, can be downloaded at the 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 is the life expectancy of Eppendorf Tubes?

At least 5 years at a storage temperature of +5 to +35 °C. If unopened and properly stored Eppendorf Tubes have shelf-life of 8 Years (standard Eppendorf Quality) or 5 Years on a purity grade (Biopur, PCRclean, Sterile, Forensic DNA Grade, ). Please observe " Instruction for Use" for storage condition recommendations: - Instruction for Use (IFU) of Tubes - Conical tubes, SafeCode tubes and SnapTec tubes - Instruction for Use of 5 mL Tubes - Instruction für Use of LoBind Tubes

From what material are Eppendorf Tubes manufactured?

All Eppendorf Tubes are manufactured from virgin polypropylene. The used polypropylene (PP) fulfils the specifications of the FDA for the use of plastics for foodstuffs. During production, no slip agents, biocides, or plasticizers are used. Colorants are free of biological material, free of heavy metals, and free of melamine. No metal-based dyes are used. Please see General Quality Certificate for epT.I.P.S, Combitips ® advanced, ViscoTip, Tubes, Plates, UVette.

Do you offer siliconized micro test tubes?
