ep Dualfilter T.I.P.S.® Forensic DNA Grade Pipette Tips
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 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 ensures full sample recovery and the customary quick pipetting.

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.

• DNA applications (e.g. PCR)
• RNA applications (e.g. gene expression analysis)
• Protein applications (e.g. antibody research)
• Cell culture applications (e.g. media)
• Applications with radio actives
• All applications which use aerosol binding liquids
• For applications in 384-microplate format we recommend using 16 or 24-channel pipettes together with ep Dualfilter T.I.P.S. 384
