Supplier: Liebherr
These spark-free laboratory freezers feature static cooling with an electronic controller system ensuring high temperature consistency and uniform temperature distribution.

The controller stores the minimum and maximum interior temperatures, the last three temperature alarms and power failures, together with the time, date and duration of the alarm. The digital display indicates the exact temperature and the operating status. The refrigerant used is a hydrocarbon.
