Laboratory freezers are used to keep samples or specimens cold for long periods of time. Refrigeration units for keeping blood plasma and other blood products, as well as vaccinations and other medical or pharmaceutical supplies, are examples of what they comprise. They vary from regular refrigerators used in homes or restaurants in that they must be thoroughly sanitary as well as absolutely dependable. There are five fundamental components in every refrigeration cycle: fluid refrigerant; a compressor, which regulates the flow of refrigerant; condenser coils (on the exterior of the fridge); evaporator coils (on the interior of the fridge); and an expansion mechanism. Freon gas suppliers in UAE supplies refrigerant gases UAE uses in their refrigerators. Now coming down to laboratory refrigerators. The discharge of gases from the contents, the presence of incompatible chemicals, and spillage are all potential risks presented by laboratory refrigerators and freezers. Only freezers designed for laboratory usage should be used to store chemicals.

Different Types:

General Purpose: 

General laboratory refrigerators and freezers are household appliances that have historically been used to store food and drinks. While they are not normally ideal for use in a laboratory, they may be used to store aqueous solutions. These units should not be used to store combustible goods. Food and beverages are not permitted, and the units must be clearly labeled as such.

Combustible: 

Refrigerators and freezers made of flammable materials are intended for the storage of flammable substances and liquids. There is no internal switching or wiring that may cause an arc, spark, or produce an ignition source. To decrease the possibility of flammable vapors being ignited, the compressor and associated circuits are often situated near the top of the machine. Thresholds, self-closing doors, and magnetic door gaskets are also included in these freezers. If an exothermic reaction occurs inside the storage compartment, special inner shell materials reduce damage. Keep an eye out for flammable storage units, which should be noted on the unit's label.

Explosion Proof: 

These units are intended to be used in places where the environment outside the unit may turn explosive. These are normally not required in a typical laboratory environment. 

Temperature Range Capability

Although there are exceptions, laboratory refrigerators normally function between 2°C and 10°C. It is preferable to use a refrigerator that closely matches temperature requirements since the lower the temperature, the more electricity it uses. Laboratory refrigerator controls may vary from a basic dial thermostat (cold, colder, coldest) to a complex digital LED display with precise programmed logic controls.

Low-humidity laboratory freezers reduce moisture in the surrounding air. Reduced-humidity laboratory freezers are intended for seed storage and applications where the refrigerator doors are often opened and closed. An automated defrost option is another useful feature. This maintains the refrigerator frost-free and operating at peak efficiency. The compressor turns off during an automated defrost cycle, and the fan pushes air over the coils to eliminate ice. An internal fan pumps air throughout the refrigerator, ensuring that the temperature remains constant. When it is critical to keep samples from drying out, laboratory freezers with manual defrost mechanisms are advised.

Some laboratory refrigerators include bypass refrigeration and microprocessor-based controls for speedier pull-down and recovery times. A rear-wall plenum with a heatsink on the plenum or the floor may assist to reduce temperature increase.

Design

When choosing a laboratory refrigerator, it is essential to examine the available space. If there isn't enough room in the laboratory, the refrigerator may be placed on the wall or integrated into another equipment. Some laboratory freezers are designed to fit under a laboratory counter. Because of their small size, space-saving designs are more subject to temperature variations. There are also larger stand-alone units available.

The majority of laboratory refrigerators have one or more solid doors or sliding glass doors. Locking the freezers prevents unauthorized workers from obtaining harmful products such as clinical samples, drugs, and vaccinations.
