ABSTRACT:
The present investigation deals with the experimental study carried out for a variety of volumetric wares such as fixed volume pipettes, graduated pipettes, graduated burettes, volumetric flasks and micropipettes used in various analytical and biological studies in our laboratory. It takes into account not only manufacturers tolerances for various types of glassware but attempts to estimate the systematic and random errors during their use. This leads to knowing the Inaccuracy and Imprecision of volumetric wares. A series of fill- and- weigh or fill-delivery- weigh operations using water are performed in the exercise to get the experimental standard deviation. Thus this experimental study is useful for knowing the uncertainty estimate of volumetric wares. Moreover it may be emphasized that systematic and random variation inherent in the volumetric glassware has not been really included in the stated tolerance of the glassware by the manufacturers. Hence evaluation of the same was essential and we have carried out the same in this study. The problem of uncertainty in the performance of laboratory glassware was analysed using cause-and – effect analysis. Uncertainty sources were identified and combined uncertainty was estimated.
