CM ICH series has an accuracy temperature and humidity control in order to ensure stability parameters of these variables according with the directive ICH Q1A (R2) Stability Testing of New Drug Substances and Products and US FDA 21 CFR part 11. These equipments comply with the three studies in those directives: large and middle duration or accelerated.
It’s possible to adapt the chamber the chamber for the photostability test according with the directive: ICH Q1B Photostability Testing of New Drug Substances and Products, option 2.

Our laboratory, LCIS, is the responsible to do the qualification of the chambers: DQ, IQ, OQ or PQ.
