Laboratory Refrigerator- a High End Gadget

The omniscient Wikipedia tells us that a'refrigerator is a device that is similar to a refrigerator',the only difference being that the former maintains a temperature below the freezing point of water whereas the latter maintains a temperature a few degrees above the freezing point of water.Lower temperatures,in a confined volume,lowers the reproduction rate of bacteria,so refrigeration or freezing reduces the rate of spoilage.Refrigerator units are used both in households and commercially.Commercial refrigerators units were in use for almost 40 years prior to the common home models.Commercial refrigerators are being extensively used in shops,restaurants and bars.These appliances are ideal for storing frozen products,like meat,ice creams,cheese,butter and many other essential items.Even various hospitals and laboratories are using refrigerators to preserve their important medicines,chemicals and samples.

Laboratory refrigerator normally store samples at a temperature between-25 and-15 degrees Celsius and often include equipment for storing samples and special instruments used for conducting experiments that require precise temperature control.While a household refrigerator has its temperature in the range of 0 to-10 Celsius,a laboratory refrigerator may go as low as-85 degrees Celsius.These refrigerators are used for a variety of purposes,such as storing samples of RNA and DNA,serums and tissue samples,protein extracts,and bacteria strains.In hospitals they can be used to preserve organs and blood.Since all these items are prone to degrade over time,freezing is essential to preserve them.So a laboratory refrigerator is not just a bigger refrigerator but a high end gadget that is used to store materials that require constant,regulated temperature without spoiling.

A general purpose laboratory refrigerator may look just like a home refrigerator with shelves both inside and in the door,and rubber gaskets that prevent warm air from entering.They can be locked,and usually have an LCD temperature display that allows you to keep an eye on the temperature without having to open the lab refrigerator to check.An ordinary refrigerator may not able to maintain the temperature during the times when the door may be opened.The laboratory refrigerator door may have to be opened several times in a day,but the heavy duty refrigeration used needs to ensure that the preset temperature will be maintained in spite of the frequent door opening.There are different types of lab refrigerators available in the market,including liquid nitrogen refrigerators that can reach temperatures as low as-190 to-196 degrees Celsius.There are also refrigerators that are like walk-in closets,which provide up to 1,000 cubic feet of storage.These walk-in refrigerators do not generally reach the same extremes in temperature as liquid nitrogen refrigerators.Some refrigerators may have accessories like thermometers and alarm systems to help keep an eye on the temperature and any snags that might come up.A laboratory refrigerator is a crucial part of any laboratory,and if taken proper care of,it will serve you for years.
