These mini pipettes include a two step plunger that facilitates super blowout from the tip (last drop dispensing), resulting in very high accuracy and precision. This allows the mini pipette to be used for reverse pipetting and repetitive pipetting. The tip cone of the 5μl, 10μl, and 20μl mini pipettes is designed to accept both standard 200μl tips or ultra micro tips up to 20μl. Use of ultra micro tips for volumes up to 20μl enhances accuracy and precision. Can be used for reverse pipetting and repetitive pipetting. These pipettes provide an optimum length of 130mm for user comfort during pipetting, and are fully autoclavable at 121°C, 15 psi for 10 to 15 minutes. Plungers are color coded for different volumes for easy identification in the lab.
