pipetteMicropipettors are used for the accurate delivery of small volumes.

  • Pipettors are sent to the manufacturer annually for cleaning, preventive maintenance, calibration, and adjustment, if necessary. Preventive maintenance dates are recorded in the LIMS. Preventive maintenance includes a new seal and piston cleaning annually, and a new shaft and reconditioned piston every 3 years. Calibration records are stored in the pipettor logbook.
