Increasingly, pharmaceutical scientists must not only be specialists in their field but must also be familiar with legislation that governs the use of equipment in their industry. The regulation of test and measuring equipment changes continually as new regulations are introduced and new equipment is developed. Calibration in the Pharmaceutical Laboratory provides general background on laboratory balances and precision scales, insight into mass measurements and associated errors, and detailed information on key quality issues associated with weighing. Managers responsible for QC and QA will find this book an invaluable tool when setting out SOPs for balances and scales used throughout the manufacturing and testing process.
