EPPENDORF Tubes® 3810X
The easy–open, easy–close design of the Eppendorf Tubes® 3810X provides convenient, ergonomic, and reliable one-handed operation. Whether sample preparation, centrifugation or storage – the Eppendorf Tubes® 3810X fit perfectly into your workflows!
Known to some as Eppendorf’s Standard Micro Test Tube 3810X, the successor to Eppendorf’s renowned Micro Test Tube 3810 continues to define PCR tube standards of excellence in the laboratory.
Known throughout the industry as as Eppendorf Tubes these combine the tried and tested features of the classic Eppendorf tube with new, invaluable features.
Perfect sealing
Excellent chemical stability
Optimal construction materials
Guaranteed better resistance to centrifugal force.
Product Features
Flat, frosted lid and writing surface on body of tube offer generous labeling area
Easy to open and close thanks to improved lid geometry
Graduation from 0.1 mL to 1.5 mL on body of tube
Autoclavable when open (121°C, 20 min)
Can be centrifuged at up to 25,000 x g in fixed-angle rotor (up to 70,000 x g possible in swing-bucket rotor)
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.
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.
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.
Yes, the batch-specific purity grades can be downloaded at our <a href="https://www.eppendorf.com/certificates" target="_blank">certificates homepage</a>.
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.
All of our tubes are manufactured from polypropylene. The polypropylene we use fulfils the specifications of the FDA for the use of plastics for foodstuffs. No metal-based dyes are used.
Our tube assortment does not include coated or siliconized tubes. In order to keep sample loss caused by the adsorption of sample material on the tube wall to a minimum, we recommend using the Eppendorf Protein LoBind Tubes or Eppendorf DNA LoBind Tubes. These are made of a special type of polypropylene and are manufactured under optimized process conditions.
Yes, this is possible. Please note that the micro test tubes have to be taken out of the packaging for sterilization.<br />In addition, please note that some ethylene oxide will remain in the material after sterilization.
No. Bacterial endotoxins (lipopolysaccharide, LPS) are very stable and withstand normal autoclaving at 121 °C. To inactivate LPS, the objects have to be baked at 250 °C, which, of course, is not possible with plastics.
Our tubes are not produced from antistatic material, i.e. they are basically not antistatic. But it should be noted that the use of antistatic agents during production will destroy or reduce the wettability of the tubes.
All micro test tubes designated with "PCR clean" are free of human DNA, DNase, RNase and PCR inhibitors. Our Safe-Lock micro test tubes are also available in the "Eppendorf Biopur" purity standard. Due to the special manufacturing processes and the individual blister-packaging, Biopur products are certified "DNA free".
Our micro test tubes are used both in the proteomics area and for storage and transport of many different protein solutions. If you work with low protein concentrations, we recommend using the Eppendorf Protein LoBind Tubes. These tubes are made of a special type of polypropylene and are manufactured under optimized process conditions. In comparison to standard polypropylene tubes, these tubes therefore demonstrate a considerably lower affinity to proteins.
The micro test tube should be clean and free from grease and only labeled on the space provided. Water-resistant felt pens from Steadtler S and F, in black, are the most suitable for this. The writing should be left to dry for at least 2 min.
Lead, cadmium, mercury, etc. are well below the prescribed limits of the DIN norm. In the course of the production process it is impossible to avoid the smallest quantities of metal resulting from machine friction.
Safe-Lock 0.5 mL: 30,000 x g / Biopur 22,000 x g / DNA LoBind 30,000 x g / Protein LoBind 18,000 x g<br />Safe-Lock 1.5 mL: 30,000 x g / Biopur 22,000 x g / DNA LoBind 30,000 x g / Protein LoBind 18,000 x g<br />Safe-Lock 2.0 mL: 25,000 x g / Biopur 22,000 x g / DNA LoBind 25,000 x g / Protein LoBind 18,000 x g<br />3810X: 30,000 x g<br />3810: 25,000 x g<br /><br />When using form-fitting tubes and buckets and filling the tubes with their nominal volume, centrifugation of the Safe-Lock Tubes at 25 °C for 30 min at up to 70,000 x g (RT) is possible. Tubes can be centrifuged in a 45°-fixed-angle rotor at 40 °C sample temperature and 90 min with aqueous saline solution (density 1.0 g/ml) up to the above g-forces. The centrifugation resistance depends on the temperature and will be lower at sample temperatures of > 40 °C. Liquids with a higher density or affect the stability of the tubes (organic solvents, acids) may reduce the mechanical resilience of the tubes.
