Ultra-low Temperature Freezer

Ultra-low Temperature Freezer -86 ºC
Ultra-low Temperature Freezer
Freezers have two independent refrigeration systems to provide the highest levels of sample security.
Dual Cooling System for a backup system to ensure the integrity of samples is not put at risk and cabinet design with enhanced insulation performance and storage capacity.
If one refrigeration system fails, the other refrigeration system activate to maintain a temperature of up to - 70ºC.
The Dual Cooling System is designated to securely store valuable biological samples.
It is consist of two individual compressors to provide a reliable -86ºC Ultra-Low temperature environment.
