epT.I.P.S. LoRetention pipette tips and ep Dualfilter T.I.P.S. LoRetention filter tips are particularly well-suited for applications with samples that contain detergents. Detergents or detergent containing liquids lower the liquid’s surface tension. This leads to a phenomenon called “wetting”: Residual liquid sticks to the tip wall and cannot be recovered. The invisible film left behind in standard tips shows a significantly high amount of valuable sample material, which becomes discarded together with the tip. 
 
Particularly when it comes to sensitive PCR and real-time PCR applications, low retention surfaces can increase the reproducibility and significantly reduce the loss of expensive reagents. 
 
The low retention property of epT.I.P.S. LoRetention pipette tips and ep Dualfilter T.I.P.S. LoRetention filter tips is generated by an ultrahydrophobic, extremely homogeneous surface. It is achieved through an innovative treatment at the molecular level – the “Pearl Effect” Technology. All pipette tips are uncoated, free of additives and do not leach into the sample. Liquids containing detergents simply roll off, so that practically no liquid remains in the tip. These outstanding material properties guarantee maximum sample recovery for cost saving and improved reproducibility.
