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.

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.

Do the Eppendorf LoBind Tubes have the same material durability as all other micro test tubes from Eppendorf?

The Eppendorf LoBind Tubes completely satisfy the specifications of the Eppendorf Standard Safe Lock tubes with reference to centrifugation stability (exception: Protein LoBind Tube), lid tightness, pop up safety and chemical resistance. (See Application No. 56: The best material for original Eppis.)

Are the Eppendorf LoBind Tubes coated?

Not the Eppendorf LoBind Tubes are neither siliconized nor coated. The low binding affinity results from of a special type of polypropylene and the optimized manucturing process.

Can I use the Protein LoBind Tubes regardless of whether I am working with basic or acidic proteins?

The Protein LoBind tubes show protein low binding properties for both low and high pH values.

What distinguishes the Protein LoBind Tube from a "Standard" Safe-Lock Eppendorf tube?

The Protein LoBind Tube shows, in comparison to a Safe-Lock Tube, significantly less protein binding affinity. The Protein LoBind Tube is therefore especially suitable for applications with the lowest quantities of protein.

Are the Eppendorf LoBind Tubes autoclavable?

Please note that only the LoBind Tubes with snap can are autoclaveable when opened: 121°C, 20 min. LoBind Tubes with screw cap are not autoclaveable.

Are Eppendorf tubes and plates (also LoBind variants) resistant to 100% acetonitrile?

Eppendorf tubes and plates including LoBind variants are resistant against 100% acetonitrile only in room temperature conditions. Above 40°C and prolonged exposure (days) may lead to partial damage and is not recommended. For lower acetonitrile concentrations the resistance parameters will be better so prolonged exposure and higher temperatures may be possible. This must be however tested by the customer.
