Stability Test and Climate Cycling Chamber


The WK3-0 was designed for long term and accelerated stability tests, including ICH Q1A and ICH Q1B. It is capable of simulating the different climates and/or seasonal climates and the various climate zones of the world.

The components that have been exposed to a long-term test and/or and accelerated service life played a key role throughout the development and construction of the WK3-0.
