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.
