Climate chamber KBF 260

humiditytemperaturephotostability

Product description
The proven specialist for reliable ICH stability tests in the pharmaceutical and laboratory sector: the KBF 260 performs long‑term tests, accelerated tests and stress tests with precise climate control and comprehensive documentation options. Suitable for all installation locations thanks to flexible water supply variants. The latest KBF consumes up to 40 % less energy than the previous model. Optional light modules convert the unit for ICH photostability testing or plant growth applications.
