ELECTRIC FREEZER |
LIQUID NITROGEN FREEZER |
Economic efficiency |
It is available only with the lower cost electronic connection. |
Expensive liquid nitrogen tank and the liquid nitrogen should be supplemented consistently. |
Safety |
It is safer from pollutants. When blackout, it secures safety with BACK UP SYSTEM if the tempera- ture goes up. |
It has a risk to be contaminated by bacteria or fungi inside the tank |
Accuracy |
Temperature difference between the upper part and the lower part inside is ±5°C, so the tempera- ture is more even. |
The temperature of the lower part inside the tank is -196°C, and the upper part is -70°C. The temperature difference is huge. This has a significant impact on viability of stem cell. |
Conve- nience |
Internal space can be used efficiently for keeping samples, and it is simple to perform work. |
Rack for keeping samples is very inconvenient for sample work because of the liquid nitrogen tank’s structure, and it is difficult to use the space inside the tank efficiently. |
Control system
■ Alarm system and safety devices
■ Functions for setting double passwords to prevent access or control except administrators
■ Data locking function
Alarm system and safety devices
■ Alarm for filter cleaning period (Warm Condenser alarm)
■ Alarm for high/low temperature of sight and auditory
■ Equipped with pressure switch
■ Equipped with overheating prevention switch
■ Auto return system after blackout
