WUF Ultra Low Temperature Freezer uses the high qualified parts and has the simplest structure
for superior temperature stabilization in the chamber. However, in case of sudden power failure,
temperature in the device could be increased and it may cause damage of samples in the
chamber.

temperature is abnormally increased, LCO2 gas is automatically dispersed and the system beeps.
