These ultra-low temperature freezers with climate-neutral refrigerants (R-290 and R-170) offer safe, long-term storage of biological and chemical samples within a temperature range of -90 to -40°C (-130 to -40°F). The freezers guarantee a constant low temperature that can be adjusted to an accuracy of one degree. The ambient temperature is monitored by a controller, which emits a visual or acoustic alarm if a preset value is exceeded.
A multi-level safety concept protects against unauthorized access. The door can be opened using a door latch handle or an electromechanical door locking mechanism. You can also lock the temperature controller's keypad to ensure maximum security and password-protect the adjustment menus.
Additional features include an ergonomic door handle, thermal insulation with vacuum insulation panels, Ethernet interface, internal data logger, and operating hours counter.
