This setup has a control setup that moves the conditions in this unit from 4 to -20 degrees Celsius. It uses a key lock and keeps samples and reagents safe. This uses organized items and works with a safety key lock, temperature display and thermostat to make the temperatures easy to manage. The thermostat is also made to regular items right. There are four adjustable shelves here plus two aluminum fixed shelves with three drawers in the UBF model. The UBR model has an internal lamp too.
