According to the EU GMP guidelines, raw materials should preferably be weighed in a separate weighing chamber intended for this purpose.
The aim should be to achieve a spatial separation of the direct production or laboratory environment. The position of the weighing chamber plays a special role in this process.
Consideration must also be given to access control for personnel, an undisrupted material flow, the cleaning of accessory materials may be required before weighing, as well as the controlled disposal of empty containers and other consumables.
These measures are used, among other things, to avoid confusions, mix-ups and contaminations of the item being weighed.
