ABSTRACT
Recalibration of 250ml volumetric flask from time to time is very vital for determination of its accuracy and precision compared with its original manufacturers calibration. It gives a sound understanding of modern measurement methods and knowledge of equipment used. Glass is known to play an important role in the modern technology as it is used in the production of laboratory apparatus, e.g. volumetric flask, measuring cylinder etc. from this project work, it was shown in chapter three and four that recalibration is all about quantitative measurement and the process of checking a measuring system of equipment readings against a higher reference standard. The results in chapter four were checked against the tolerance of class a volumetric flask in table one.
It was also shown that expansion and contraction, which is due to temperature changes, has taken place in the internal component of the flask.
