To calibrate a 25 ml volumetric pipette to calibrate a 100 ml volumetric flask to calibrate a 50 ml measuring cylinder introduction the purpose of this experiment is to study the relationship of several types of volumetric glassware and the accuracy of measuring the volumes of liquids very precisely in quantitative laboratory work. Laboratory experiment 1 calibration of volumetric glassware an important trait of a good analyst is the ability to extract the best possible data from his. 3 label the 4 plastic bottles, one for each different volumetric device to be calibrated, with an identifying tag for each of the pieces of glassware that you will calibrate cap the bottles and weigh to the nearest 01 milligram record the masses 4 using the 10-ml volumetric pipet, transfer a water sample to the appropriately labeled bottle.
Introductory experiment: calibration of volumetric glassware introduction volumetric glassware, for the beginning and accomplished analytical chemist, is probably. After correct calibration class b glassware can be used to perform analysis with the same accuracy as class a glassware however, b class glassware is usually of lower quality, so we may expect higher thermal expansion coefficients and lower resistance to chemicals.
