Full-service support: Cleanroom qualification and calibration

at Losan Pharma GmbH, Neuenburg

Losan Pharma GmbH develops and produces solid, oral drugs for notable pharmaceutical manufacturers. In addition to the production of various solids, the products are assembled and packaged, e.g. in stick packs, blister packs or tubs. In Neuenburg, Losan Pharma operates cleanrooms of classes C and D and ISO classes 7, 8 and 9.

In 2006, Testo Industrial Services performed the first qualification of cleanrooms and HVAC systems within the course of extension of production facilities at the Neuenburg site. Since then, the re-qualification of cleanrooms and the calibration of stationary systems, measuring systems and test equipment have been the focus of cooperation. In addition to end-to-end support, resources for events such as shutdowns, campaigns and new buildings are managed flexibly and according to expenditure.
