Create the perfect fit with FlexFit

FlexFit technology provides a superior fit and secure seal for precise and accurate pipetting. This patented feature provides flexibility on the proximal end of tips, dramatically minimizing the necessary insertion and ejection forces between pipettor and pipette tips, thus improving ergonomics. FlexFit is found in all uTIP Pipette Tips for universal pipettes and in all xTIP Pipette Tips for Rainin LTS-style pipettes.
