Are the ep T.I.P.S. LoRetention resistant to organic solvents?
The LoRetention tips are made from polypropylene, as are standard tips, and they are resistant to a
number of organic solvents. Further information regarding chemical resistance properties of pipette tips can be found in the User Guide no. 23: Chemical Stability of Consumables.
How are the boxes containing ep T.I.P.S. LoRetention distinguishable from those containing other ep T.I.P.S.?
The lids of the LoRetention racks and reloads have a transparent lid. Standard tips have a blue lid. A reusable LoRetention adhesive sticker is placed on the lid. This sticker also features “LoRetention” writing on the reverse side. This way previously purchased epT.I.P.S. boxes can be
labeled. When the box is open, the writing “LoRetention” will thus be easily readable.
Will foam formation, observed during pipetting of solutions containing detergent, be reduced when epT.I.PS. LoRetention are used?
Yes. Foam formation is rarely observed when LoRetention tips are used. This facilitates the handling
of these solutions and increases reproducibility.
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.
Does the blister packaging of the Biopur products contain latex?
No, the blister packaging is free from latex.
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.
Does the CombiBox fit onto Thermomixer comfort?
Can standard 1.5 or 2.0 ml micro test tubes also be used in the exchangeable thermoblock for cryo tubes?
No. Standard 1.5 to 2.0 ml micro test tubes have a diameter of approx. 11 mm and are therefore too small for the exchangeable thermoblock for cryo tubes (diameter of boreholes approx. 12.7 mm).
Do all types of Cryo tubes (1.5 to 2.0 ml) fit in the exchangeable thermoblock for cryo tubes?
All Cryo tubes with a diameter from 11.0 - 12.5 mm are suitable, regardless of the bottom shape (for example, conical or flat).
What are the dimensions (diameter, depth) of the individual bores of the exchangeable thermoblock for Cryo tubes?
Diameter = approx. 12.7 mm
Depth: Total = approx. 33 mm
Bottom shape: flat
Can you tell me the depth and the diameter of the bores of the exchangeable thermoblocks?
The specification can be found within Userguide 001: "Applications for Thermomixer comfort, Thermomixer compact and ThermoStat plus" (Please insert weblink here)
Does the thermoblock for microtest plates have a lid?
Yes. When the exchangeable thermoblock for MTP block is ordered, the lid is delivered in the same packaging. It can also be ordered separately (order no.: 5363 000.217).
Can 24-well cultivation plates be used in the exchangeable thermoblock for MTPs and deepwell plates?
No. The thermoblock for MTP is designed for the globally recognized standard microplate with dimensions of 127 x 86 mm. The microtiter plates for cultures have larger dimensions (132 x 88 mm) and therefore do not fit in this block.
Which slides fit into the exchangeable thermoblock for 4 slides (Order no. 5368 000.010)?
The exchangeable thermoblock 'slides' can be used for all glass slides of 75-76.5 mm length, 25-26 mm width and a height of up to 1.2 mm. This thermoblock is well suited for all types of hybridization reactions such as microarray hybridization or fluorescence in situ hybridization (FISH). Application notes descibing the use of thermoblock 'slides' for those kind of applications can be found on our homepage (Please insert web-link here).
Is the exchangeable thermoblock for slides compatible with the Eppendorf DualChip Microarrays?
No. For the DualChip Microarrays, an exchangeable thermoblock is required that applies additional pressure to the hybridization frames. This reduces potential evaporation to a minimum.
Can the IsoRack be centrifuged?
Please note that we offer a special IsoRack adapter for our 5810/R (swing-bucket rotor type A-4-81, flex buckets). In addition, the IsoRacks can also be centrifuged in the A-2-DWP and in the A-4-62-MTP. In this case, centrifugation is limited to a max. rotational speed of 3,700 rpm (max. 1,000 centrifugations).
Are the cool packs (Isopack) of the IsoTherm-System available individually?
Can the IsoSafe insulation box of the IsoTherm-System be autoclaved?
What are IsoPacks made of?
They are made of polyethylene and filled with a special, non-toxic liquid. The bottom is covered with an aluminum foil.
Are the IsoPacks resistant to sodium hypochloride (NaOCl)?
NaOCl attacks the aluminum foil (for both packs sizes) slightly. Over a period of eight hours or more, this may lead to damage. The IsoPack polyethylene housing is chemically resistant to NaOCl. Even if a leak occurs, the liquid in the IsoPack is non-toxic.
What are IsoRacks made of?
They are made of polycarbonate.
How long do IsoPacks (white, blue) maintain their temperature?
"If IsoPacks (in an IsoRack) are sealed in an insulating box (IsoSafe), a temperature of 0 °C (in the white packs) can be maintained for at least 6 hours and –21 °C (in the blue packs) for > 3 hours.
If the IsoPacks are in an open insulating box, 0 °C can be maintained for roughly 4 hours and –21 °C for 1–2 hours.
If the IsoPacks/IsoRacks are not placed in an insulating box, a temperature of 0 °C can be held for 1.5–3 hours and –21 °C can be held for 0.5–1 hour."
Can the IsoSafe be cleaned in a dishwasher?
At which speed is vortexing possible?
You can use either the touch vortexer at 3,500 rpm, or vortexing can be set to continuous by setting the mixing rate and mixing period to a range between 300 and 3,000 rpm. In continuous vortexing mode vortexing at mixing frequencies between 2,000 rpm and 3,000 rpm may occasionally activate the automatic imbalance detector.
During continuous vortexing the speed dropped suddenly and "TOO FAST" appeared in the display, why?
MixMate's automatic imbalance sensor, which prevents plates and tubes from jumping out during the mixing process, may be occasionally initiated during continuous vortexing at speeds between 2,000 and 3,000 rpm. Safety when mixing plates is of utmost priority, therefore this feature cannot be technically altered.
