This temperature is printed on the flask, and typically it is 20  C. During preparation of solutions with exact concentration, the first step includes transfer of an exact amount of the substance into the volumetric flask. This can be either solid material weighed on an analytical balance, or a liquid delivered with a transfer pipette. It is important that the substance is transferred to the volumetric flask without losses. 10 Example of pipette calibration A 25-ml transfer pipette is calibrated.

Manufacturers are also required to employ enough competent persons with the necessary theoretical and practical skills (paragraph 2). The manufacturer is required to have an organization chart, where each employee’s duties and responsibilities are defined, so that there is no uncertainty about the duties and responsibilities. Under item 3, specified detailed requirements for premises and equipment used during the manufacture of pharmaceuticals are given. This ensures that the final products are of high quality and at the same time the working environment of the staff is in accordance with official requirements.

Calibration is done regularly to ensure high accuracy. Analytical balances calibrate themselves by placing a standard mass on the pan. It is important never to place drug substances or samples directly on the pan, as this will contaminate the system. Therefore, the substances or the sample to be weighed should always be placed in a weighing vessel placed on the pan. First, place an empty vessel on the pan. 3 Weighing error (% relative error) due to the difference in density between the object to be weighed and the standard mass used for calibration.
