Calibrating a Volumetric Pipet
Determine the empty mass of the stoppered receiver to the nearest milligram. Transfer portion of temperature-equilibrated water to the receiver with the pipet, weigh the receiver and its contents (again, to the nearest milligram), and calculate the mass of water delivered from the difference in these masses. With the aid of Table 2-3, calculate the volume delivered. Repeat the calibration several times, and calculate the mean volume delivered and its standard deviation.
