A Persistent Problem
 

Limited volume samples; costly reagents, expensive enzymes; foaming liquids - all of which need to be pipetted with high precision..

Close visual inspection of conventional pipette tips reveals that fluid droplets or a thin film of liquid can remain in the pipette tip after dispensing. Significant factors leading to the formation of such residues are the different surface energy components of the pipette tips and the sample being pipetted, as well as their molecular composition.

The Detergent Dilemma

In biological applications such as in PCR, PAGE, or many other areas of protein chemistry, the sample must often be treated with detergent. An exact appraisal of the behavior of PP surfaces is complicated. Detergents significantly decrease the surface tension of liquids, which hinders the optimal dispensing of the liquid from the pipette tip and diminishes pipette performance.

A Slick Solution
  

The new, ultra-hydrophobic BRAND pipette and filter tips solve this problem! The surfaces of the Low Retention tips are produced through a special, patented physicochemical process. The homogeneous, defect-free surface thus produced has extremely low surface tension.

This significantly reduces sample loss and provides substantially higher reproducibility when working with critical media.
