WebPipette calibration 1. Principle: Under a constant temperature and atmospheric pressure, the density of distilled water is constant. The volume of water can be determined by weighting dispensed water. The calibration of pipette is carried out by gravimetric method. When determining the volume of water, the accuracy of measurements is effected WebAug 4, 2024 · Gravimetric testing is the most common and economical method used for pipette calibration. In this process, an aliquot of distilled water is placed in a vessel, and its weight is measured using an analytical balance. The weight is then converted to mass and then to volume using standard conversion factors, or produced by software packages. dr. anthony wang md
