WebThe HC-Lab Humidity Controller is dedicated to controlled protein crystal dehydration. The HC-Lab delivers a continuous flux of humid air with controlled Relative Humidity (RH) for the given sample temperature. The HC-Lab is able to finely adjust the RH from 30.0 % to 99.5 % (@ 23°C room temperature) with an exceptional stability of ±0.05 % RMS.
