During pipetting liquid flows through a small opening. A possible outcome of this are aerosols
(dispersion of solid or liquid particles in gas). Aerosols, drops and splashes could contaminate
the pipette and contaminations could be transferred to other samples.
To avoid these unintended and unnoticed contaminations ep Dualfilter T.I.P.S. pipette tips should
be used. The dualfilter is made up of hydrophobic polyethylene (PE). The first white layer defends
from splashes and drops and the second blue layer builds an aerosol barrier.
ep Dualfilter T.I.P.S. pipette tips are sterilized by electron beams and are certified
(see Certificates - verifiable safety for you on p. 9). ep Dualfilter T.I.P.S. pipette tips can not be
sterilized.

epT.I.P.S. LoRetention pipette tips are particularly suited to the dispensing of liquids containing
detergents. The optimized surface of the epT.I.P.S. LoRetention pipette tips counteracts the
reduced surface tension caused by detergents and also with corresponding solvents, so that the
liquid runs off without forming a film. This increases sample recovery and pipetting accuracy.
Please note:
The small amounts of residual moisture that may occur with epT.I.P.S. LoRetention pipette tips
can appear to be higher than with standard epT.I.P.S. pipette tips as the residual moisture does
not remain in the tip as a film, but collects as droplets due to the physical properties.
Due to the physical properties of the surface of epT.I.P.S. LoRetention pipette tips, the dispensing
volume is slightly lower than the nominal volume in comparison to the corresponding standard
epT.I.P.S. pipette tips when dispensing purely aqueous solutions with epT.I.P.S. LoRetention
pipette tips 0.1 – 10 μL S and 0.5 – 20 μL L. Reproducibility still has the same high performance
as standard epT.I.P.S. pipette tips.
