Laboratory Refrigerator vs. Domestic Refrigerator
It is common knowledge that biological samples should be stored in stable conditions below ambient temperature and have superb environmental control. Domestic refrigerators often have imprecise temperature control and suffer from several drawbacks:
- Temperature varies each time the door is opened, with slow recovery.
- Temperature rises during defrost cycle, putting samples at risk.
- Defrost Cycles are often based on time with no sensory feedback of actual interior temperature conditions.
- Cabinet temperature is easily affected by ambient temperatures, with risk of contents freezing if ambient temperature drops below 0°C.
- Temperature configuration by dial is inaccurate, with no digital temperature indication.
Panasonic has engineered solutions for all these problems into its laboratory-grade refrigerators, which comply to the needs of hospitals and research facilities around the world.
Unique Defrost Cycle
In the range of 4°C, frost build-up on the evaporator is inevitable, affecting the performance of the heat exchanger. However, Panasonic has solved this problem with a cycle defrost and evaporator temperature sensor system. This system runs automatically so there is no need to turn off power for defrosting.
Safety and Alarm Features
These refrigerators are fitted with warning systems, including alarms and flashing indicators to indicate high or low temperature fluctuations. The easily accessible front control panel displays actual temperatures on an LED screen with intuitive touch pad settings, making operation simple. Door locks are standard on all units to safeguard valuable contents.
Temperature Uniformity with an Efficient and Powerful Refrigeration System
For frequent door openings, Panasonic’s MPR series refrigerators are equipped with powerful, hermetically sealed compressors. These purpose-built compressors ensure superior pull-down characteristics and precise temperature control.
