These mini pipettes include a two step plunger that facilitates super blow-out from the tip (last drop dispensing), resulting in very high accuracy and precision. This allows the "Lilpet" to be used for reverse pipetting and repetitive pipetting. These pipettes provide an optimum length of 125mm for user comfort during pipetting, and are fully autoclavable at 121°C and 15psi. Plungers are color coded for different volumes for easy identification in the lab. Each pipette is individually calibrated per DIN 12650 standards. Also, the pipettes are manufactured in an ISO 9002 certified facility - calibration certificates for specific batches are available upon request.
