带 CO2 或 LN2 备用系统的 -80 °C 冷冻箱
If power is unreliable or samples cannot be replaced, this freezer adds a second line of defence. When the cabinet warms past an adjustable trigger, typically -60 to -70 °C, liquid CO2 or LN2 is injected for 24-72 h depending on cylinder. Supply pressure is 0.5-2 MPa, the controller runs on a 12 V battery, and capacity is 400-700 L.
