Features:

2 Independent Cooling System

Dual cooling system is designed with 2 independent cooling systems which provides extra insurance for Bio-samples. And dual cooling system maximizes optimal reliability .

Extreme Safety

Should one system unexpectedly fail, the other will maintain a temperature in the -70℃ range ensuring that the sensitive samples not put at risk separately.

Ultimate Cooling Performance

Under normal working conditions, the 2 independent systems start in sequence at intervals. Then 2 systems work together to get a rapid pull-down performance.

7″ LCD Touch Screen

A 7-inch LCD touch screen with Android operating system is designed for this refrigerator, to enable users to operate conveniently and quickly.

Multi-Layer Sealing Design

Multi-layer sealing can save energy and keep heat outside ,better insulation helps keep the freezer cold last long,also reduce noise during the running .

Energy Saving

The ultra-low temperature freezer adopts the unique secondary foaming technology, and the ultra-thick VIP insulation layer greatly improves the insulation effect; the VIP vacuum insulation board tightly locks the cold air to ensure the insulation effect.
