  • Experiment Laboratory Weighing

    IT DEPENDS ON THE ACCURACY YOU NEED IN THE EXPERIMENT. 1) Most experiments tell you how much accuracy you will need. Never use the analytical balance if the top-loading will do. 2) If you need to weigh to the nearest milligram ( + 0.001 g) or to the tenth of a milligram ( + 0.0001 g), then use the analytical balance, otherwise, use the top-loader.
