The combination of Peltier technology for heating, cooling and dehumidifying, as applied by Memmert in its new constant climate chambers, is so far unique on the market. Even with a high ambient temperature and in regions with extremely high or low humidity, set
temperatures and humidities are maintained exactly, since humidifying and dehumidifying are controlled digitally in the working range from 10 to 90% rh. This means that the strict requirements of the EU GMP Directive, which was supplemented on 1st June 2006 with the
obligation to perform ongoing stability tests for all pharmaceutical products, as well as the requirements of the ICH (International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use) are easily met.
Since the majority of stability tests are performed at temperatures between +20 ºC and +30 ºC, Memmert developers have fine-tuned the temperature control of the HPP specifically to the range from +5 ºC to + 70 ºC. The temperature fluctuations that are unavoidable in a
temperature control cabinet are therefore far below the required tolerances for every temperature /humidity constellation selected.
