Weighing is a basic operation in any analytical laboratory. It is possible to run a laboratory without modern analytical instruments but it is not possible to carry out analysis without a weighing balance.
Weighing is an essential requirement for preparing sample solution, reagents, titrants, precipitates, etc. The accuracy of your results will largely depend on the accuracy of your analytical balance. Precautions for correct weighing of samples discussed the need for calibration amongst other factors.
Calibration against certified standard weights will give you the confidence on your weighing. Regular calibration will guarantee the correctness of your results along with those precautions you should take in preparing your samples.
Mass metrology – Balance calibration
Incubator calibration (0 – 80°C)
