This Hamilton SoftGrip precision pipette requires 50% less actuation force than competing brands. Less user fatigue results, due to the soft ergonomic shape and low plunger force. An isolated volume adjustment ring prevents accidental volume changes. A magnified easy-to-read precision micro meter ensures eproducible, accurate volume settings. The separate tip ejector button is east to reach. Every pipette is calibrated at Hamilton with standards traceable to NIST. A certificate of calibration documenting the product's accuracy and precision is provided in the package, along with non-wettable recalibration labels for field service and recalibration. The pipette is color-coded for easy volume identification. Volume range 2.5 - 25µL; increments 0.02µL.
