Best practice Mobile weighing for clean rooms In GMP-regulated environments, the precise and fast weighing of ultrafiltration vessels, which are headed to different production areas, requires a mobile weighing solution with a hygienic design. Key facts Boehringer Ingelheim uses ultrafiltration vessels when manufacturing its pharmaceutical products under clean room conditions. These vessels must be weighed precisely and transported to other production areas or, in some cases, put into storage. When it comes to weighing them, a mobile weighing solution that can be cleaned with ease and transported safely is required. To meet Boehringer Ingelheim’s requirements, Vienna-based system manufacturer and partner to Minebea Intec Baumgartner & Co. designed a mobile process vessel with integrated weighing electronics and modules from Minebea Intec. This mobile weighing solution enables precise on-site weighing and reduces costs thanks to its flexibility and the speed with which it is ready for use again.

Its hygienic design enables complete inspections to be performed and ensures ease of cleaning to protect against contamination.

Project objective and implementation Boehringer Ingelheim relies on UDF vessels, which are put to use under clean room conditions – both after ultrafiltration and before the product filling stage. The pharmaceutical company ordered a mobile weighing solution for a 50 l ultrafiltration vessel weighing 320 kg in total. The extended remit required the solution to be resistant to cleaning products, be able to withstand transportation stresses and to include the option of connecting the weighing station to the existing PLC. Manufacturing systems used in the pharmaceutical industry have to comply with...
