Thermostatic test chamber KBF 260

climatichumiditytemperature

Product description
The KBF 260 is a constant climate chamber designed for ICH stability testing, long‑term, accelerated and stress tests in pharmaceutical applications. It meets ICH requirements for precision, programmability and documentation, offers flexible water supply options for varied installation sites and consumes up to 40% less energy than the previous model. Optional light modules enable conversion to an ICH photostability chamber or a plant growth chamber.

Benefits
