  • The volumetric apparatus. this mass is then converted to the desired volume using the tabulated density of water: volume = mass / density (eq. 1) p a g e 2 all volumetric apparati should be either purchased with a calibration certificate or calibrated by the analyst in this manner. systematic errors affecting volumetric measurements the volume occupied by a given mass of liquid varies with to ensure proper measurement of large volumes in the laboratory, volumetric apparatus should be calibrated regularly. two of the most common apparatus calibrated are volumetric flasks and serological pipettes.

    Scope. 1.1 this practice covers procedures for use in the calibration of volumetric ware, in accordance with e694 such as is in common use in chemical and clinical laboratories. calibration of a pipette and volumetric flask calibration of volumetric equipment is carried out by weighing the amount of water contained or delivered. since the density, or weight per unit volume, of water changes about 0.03 %/ oc at 25 c, the temperature of the water used in the calibration must be known. because the density of water is relatively low, a correction must be made for buoyancy
