HC-Lab - Humidity Controller

The HC-Lab is designed for crystal dehydration experiments (ref. 1 to 3). It delivers a continuous flux of humid air with a controlled Relative Humidity (RH) in the immediate crystal environment.

Moreover, the HC-Lab can be combined with the Rapid Nozzle Exchanger REX to automate the nozzle exchange between the HC-Lab humidity nozzle and the cryo nozzle while maintaining the alignment with respect to the sample/crystal.
