Figure: Burette Used in Laboratory. (i) At first the burette is placed vertically with the help of burette holder as shown in the figure. (ii) The burette is washed with distilled water keeping the stop cork open. A beaker is also placed under the burette to collect the water. (iii) Then closing the stop cork, the liquid is taken in the burette
Volumetric measurement plays a central role in the laboratory. The user has to determine the degree of accuracy required for each measurement. Based on this, he can choose the appropriate volu-metric instrument. Reliable measurements require the use of precision instruments and their proper handling. To provide a better understanding of volumet-
