On the Use of Automatic Pipets in Volume Calibration of Accountability Tanks

The applicability of automatic pipets for dispensing known volumes of water in the volume calibration of accountability tanks of tens-of-liters capacity is demonstrated. Six pipet of capacity in the approximate range 495 to 716 miililiters were calibrated using gravimetric techniques. The relative standard deviation ranged from 0.0015% to 0.0074%. The pipets were used successfully in the volume calibration of accountability tanks of tens-ofliters capacity in the Savannah River Plant.
