Laboratory refrigerators are utilized to cool samples or specimens for preservation. They include refrigeration units for storing blood plasma as well as other blood products, as well as vaccines as well as other medical or pharmaceutical supplies. They differ from standard refrigerators utilized in homes or restaurant as they need to be completely hygienic as well as totally reliable.
Laboratory refrigerators need to manage a steady temperature in order to reduce the risk of bacterial contamination as well as explosions of volatile materials. To get a high degree of accuracy the refrigerator requires air to circulate as well as a fan to sustain an even temperature at entire times. The fan turns off when the door is open to stop cold air from blowing out of the unit. Laboratory refrigerators feature separate compartments to prevent cross contamination as well as may hold specific medical supplies such as blood or vaccines.
Temperature Capability
Laboratory refrigerators naturally operate from 2°C to 10°C, although there are exceptions. It is best to use a refrigerator that closely meets temperature requires because the lower the temperature the more power it requires. The control settings for laboratory refrigerators may vary from a simple dial thermostat (cold, colder, coldest) to a sophisticated digital LED display that allows for precise programmable logic controls.
Low-humidity laboratory refrigerators diminish moisture in the ambient air. Reduced-humidity laboratory refrigerators are developed for seed storage as well as applications in which the refrigerator doors are opened as well as closed frequently. Another helpful feature is an automatic defrost function. This keeps the refrigerator frost-free as well as running at best capacity. In an automatic unfreeze cycle, the compressor shuts off as well as the fan blows air over the coils to remove the frost. An internal fan circulates the air throughout the refrigerator stying the temperature uniform. Laboratory refrigerators with manual defrost systems are recommended while it is important to defend samples from drying out.
For faster pull-down and recovery times, some laboratory refrigerators are capable of with features such as bypass refrigeration as well as microprocessor-based controls. A rear-wall plenum as well as heatsink on either the plenum or the floor may assist to limit the temperature rise.
Types
There are four types of laboratory refrigerators.
Explosion proof refrigerators are developed to store flammable liquids as well as hazardous chemical substances. A lack of electrical equipment prevents fire cause by sparks in the storage area, making it safe to use with flammable materials.
Lab fridges are designed to sustain consistent temperatures as well as monitor the temperatures with digital displays. They are broad lab grade refrigerator and require to include lockable easy-to-clean sections. They are also utilized to cool samples as well as for preservation.
Blood bank refrigerators comply with all American as well as European regulations. Reliability is critical for this type, along with the capability to monitor temperatures. They also require having separate compartments for storing dissimilar sample types.
Chromatography refrigerators are developed for research experiments. They are finest used for laboratories where medical samples as well as procedures require accurate temperature settings and stability. For example, a lab refrigerator might be utilized to set up a chromatography apparatus within the refrigerator chamber.
