Abstract

A study to identify the effect of changes in vessel cross-sectional area to the mass evaporation rate of micropipette calibration without evaporation trap at nominal value of 20 µl is still being tested. Three different vessels with various diameter values of 5.9 mm, 9.8 mm and 13.7 mm were used to determine their effect to evaporation. The result of the test showed that the smaller diameter of vessel reduced the mass evaporation rate on micropipette calibration.
