Take advantage of an additional barrier in your filter pipette tip!
ep Dualfilter T.I.P.S. from Eppendorf are filter pipette 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 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 tip cone functions as a second barrier from contamination, and reliably binds biomolecules. A defined air passage rate ensures full sample recovery and the customary quick pipetting you’re used to.
1) An aerosol is a colloid of fine solid particles or liquid droplets in air or another gas.
Scientifically proven – No filter tip protects better than ep Dualfilter T.I.P.S.!
In a blind trial at the Fraunhofer Institute for Toxicology and Experimental Medicine (ITEM) in Hanover, Germany, ep Dualfilter T.I.P.S. were much better at protecting against aerosols than other commercially available filter pipette tips.
In a further study, ep Dualfilter T.I.P.S. SealMax filter pipette tips have even been tested for filtration performance under the standard EN 29463 – Standard of filtration performance testing of filters – yielding a minimum particle collection efficiency of 99.5 % with test aerosol particles sizes of 0.05 – 0.5 µm – making them ideal for applications in clean rooms and in the pharmaceutical industry.
ep Dualfilter T.I.P.S. in the purity grade PCR clean / Sterile are sterilized by electron beams, certified pyrogen-free and PCR clean (free from human DNA, DNase, RNase and PCR-inhibiting substances). ep Dualfilter T.I.P.S. Forensic DNA Grade are free of detectable Human DNA, DNase, RNase and PCR inhibitors.
