The stability cabinets of Hettich Benelux have been developed for testing pharmaceutical, chemical and cosmetic products according to ICHQ1A. They have accurate temperature and humidity control. Due to the unique air circulation system, it is possible to validate the entire shelf so that it can be used fully. As a result, the usable shelf area is maximise and by making efficient use of the shelves the PSC has a very small footprint "compared to the competition".
