For physical reasons, pipette tips made from standard materials will always retain a liquid film during pipetting of liquids containing detergents. The extent of the residual film will vary according to application and handling. This effect may lead to loss of valuable sample material as well as impaired dispensing precision. The experiments described here demonstrate that the Eppendorf epT.I.P.S. LoRetention retain dramatically less residual liquid after use with various test solutions. Consequently, loss of material is minimized and high pipetting precision is maintained.
The properties regarding flow behavior of different “low retention” pipette tips were examined by absorbance measurement in the Eppendorf BioPhotometer plus. It became apparent that the Eppendorf ep.T.I.P.S. LoRetention consistently retained the smallest amount of liquid, while achieving the highest pipetting precision, when compared to competitors’ tips.
