ANALYSIS OF THE ACCURACY OF MEASUREMENT ACCURACY OF MASS AND DOSING EQUIPMENT UNDER LABORATORY CONDITIONS

This article considers methods for evaluating measurement accuracy of mass and dosing equipment used in laboratory conditions. In the case of different types of scales and dispensers, clarity was analyzed during typical laboratory operations. A mathematical model of the measurement process was developed, thanks to which systematic and random errors were taken into account. The results of experiments with various substances are presented. Dosing errors and weight deviations were evaluated based on equipment specifications. The scientific novelty of the study was substantiated and recommendations were made on the conditions of selection and use of the equipment to guarantee the accuracy of the supply
