Protein crystallization cabinets are used for determination of a three-dimensional structure of a protein according to the hanging drop or sitting drop method of vapour diffusion. RUMED® protein crystallization cabinets effect a uniform temperature distribution in space. The cooling technology is designed in such a way, that also temperatures below the ambient temperature can be run. For cooling, RUMED® applies a vibration-free, powerful, low-noise and eco-friendly compressor technology and natural refrigerants. The integrated Control2015touch ensures intuitive operation and allows convenient control and documentation of the program flow. Due to the USB and Ethernet interface, external data evaluation is possible.
