SelecTips™ are purposely designed to exactly fit selected brands or selected models of single-channel, multi-channel or electronic pipettors. Selected pipettor specifications and guarantees are exceeded to assure reliability and to guarantee subsequent optimum performance. The shank area of each SelecTip™ is specifically engineered to position itself exactly onto the shaft contour of the selected pipettor. This assures that liquid displacement and its proportional pressure are reproducible, accurate and precise every time. A snug, airtight fit is further enhanced with the selected positioning of fin-like sealing rings which are placed in the SelecTip™'s upper shank area.
