Eppendorf Part No. 4982000322
Serial pipetting made easy The Repeater M4 makes performing long pipetting series easier and faster. The aspirated liquid can be dispensed up to 100 times without refilling the tip. An Eppendorf Combitip advanced, in the required size, is simply attached and automatically recognized via a sensor in the Repeater M4. The volume is set using the selection dial and is automatically shown in the display. Now all you have to do is aspirate the liquid with the filling lever. The desired volume can now be dispensed in several steps with the utmost precision. Dispense the same volume up to 100 times without refilling the tip—a logical solution for filling 96-well plates. The executed dispensing steps are counted using the new step counter and shown in the easy-to-read display. After use, the Combitip advanced is simply ejected by pushing a button and disposed of without the risk of contamination or having to touch the tip. Simple operation, unique flexibility and significant time savings make the Repeater M4 an important liquid handling tool for both novel research and routine tasks. Repeater M4, includes Repeater M4, Combitip Rack, Combitip assortment pack and wall/carousel holder.

United Scientific Supplies Part No. T5ML-N
Manufactured in a precision molding facility from 100% virgin polypropylene, United micropipette tips are DNase, RNase and Pyrogen free. The highly smooth surface is hydrophobic to provide low liquid retention, increased accuracy and repeatability. Inner radial rings enable an airtight grip on the tip cone. Autoclavable at 121°C and 15 psi for 30 minutes.

The Eppendorf Combitips have been completely redesigned and optimized to meet the increased requirements of a modern laboratory to a greater extent than ever before. The result is the Combitips advanced®. As they offer a wide variety of advantages in comparison with the Combitips plus, we talk about the 360° Evolution!

The ultimate protection of pipette and sample against unintentional and unnoticed contamination by aerosols, drops and splashes ep Dualfilter T.I.P.S. filter tips are filter tips with a two-phase filter for contamination protection. The two filter layers made of flexible, hydrophobic material, fit perfectly in the tip cone and retain practically 100 % of all aerosols 1) and biomolecules. This filtering effect is achieved using various, well-defined pore sizes. The layer facing the sample provides protection from drops, splashes and aerosols. The layer facing the pipette cone functions as a second barrier from contamination, and dependably binds biomolecules. A defined air passage rate guarantees full sample recovery and the customary quick pipetting. Scientifically Proven - No filter protects better than ep Dualfilter T.I.P.S.! Filter tips from various manufacturers were tested in a blind trial at the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) in Hanover, Germany. Testing focused on the prevention of pipette cone contamination by aerosols. Filter effect with regard to salt aerosols and biomolecules (DNA fragments) was examined. Quantitative determination of DNA fragments was performed using real-time PCR. The results indicate that ep Dualfilter T.I.P.S. are much better at protecting against aerosols than other commercially available filter tips. With regard to particle permeability (0.13 % +/- 0.11 %), ep Dualfilter T.I.P.S. are 55 to 677 times more effective than the filter tips tested from other manufacturers. ep Dualfilter T.I.P.S. were 21 to 600 times more effective when protection against DNA fragments was examined (0.02 % +/- 0.01 %). The worst measured results were for particle permeability 88.00 % +/- 7.00 % and for DNA permeability 12.00 % +/- 5.20 %. All filters of Eppendorf ep Dualfilter T.I.P.S., ep Dualfilter T.I.P.S. LoRetention and ep Dualfilter T.I.P.S. SealMax, are made of the same Polyethylene (PE) and have comparable pore size structure. For efficiency testing of filter tips no standardized test method exists. Thus a further study with ep Dualfilter T.I.P.S. SealMax was done based on the standard EN 1822. This standard deals with filtration performance testing of filters as used, for example, for applications in clean room technology or pharmaceutical industry. The results of the filter efficiency testing done by a certified institute showed a minimum particle collection efficiency of the ep Dualfilter T.I.P:S. SealMax of 99.5 % with NaCI aerosol particles sizes of 0.05 - 0.5 µm. All ep Dualfilter T.I.P.S. are sterilized by electron beams, certified pyrogen-free and PCR clean (free from human DNA, DNase, RNase and PCR-inhibiting substances). Features Dual protection against aerosols1) and biomolecules Dual protection for pipette and sample Free of PCR inhibitor additives Available in Eppendorf PCR clean/Sterile (sterile and pyrogen-free) and Eppendorf Forensic DNA Grade Tested at the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) in Hannover, Germany Continuous inspection of each production lot by an independent laboratory Lot-specific certificates are available 1) An aerosol is a colloid of fine solid particles or liquid droplets, in air or another gas.
