Pipette Tracker 3.3 is a cost-effective software solution for gravimetric pipette and device calibrations that reduces the time and resources required for scheduling, performing and documenting calibration checks. Pipette Tracker is very flexible allowing for custom protocols, based on a laboratory’s internal SOPs to be configured, saved and used at run-time and it is a fundamental part of Good Laboratory Practice (GLP) where precise volumes of fluid need transferring or diluting.
