Abstract
The analytical balance is one of the measuring instruments most used in the laboratory and essentially all analytical results depend on it. Modern analytical balances, which can cover ranges of reading accuracy of about 0.1 g to 0.1 mg, are now so well developed that the use of special weighing rooms are no longer needed. However, the mere use of electronic circuits does not eliminate the system’s interactions with the environment. From these, physical effects are the most important since they can not be suppressed. The information contained in this text aims to indicate the most important points to be considered during the weighing process.
