How Lab Freezers are used

Although Lab freezers may look like freezers used in your home or perhaps slightly bigger than it, they are used to store critical materials, some of which are hazardous. These lab materials are also to be kept at constant, regulated temperature. Some lab freezers are small and can fit underneath a counter, some are regularly-sized upright freezers and there are those that are extremely large similar to a walk-in freezer. Our home freezers only reach up to -10 degrees Celcius, but the coldest lab freezer can be kept at a low temperature of -85 degrees Celcius.

There are many uses of lab freezers. You can find strong serums and tissue samples, bacteria strains, samples of DNA and RNA, and protein extracts in a lab freezer. In hospitals, lab freezers are used to preserve organs and blood while pharmacies use their freezers to keep medicines. To prevent degradation of specimens, they are kept in the lab freezer t constant temperature.

You can also find a general purpose lab freezer which is similar to a home refrigeration unit. And just like a home refrigerator, these lab freezers also have shelves inside and in the doors and in order to prevent the escape of the cold, there are rubber gaskets to protect it. Their temperatures, though, are lower than our refrigerators since theirs is usually kept between -15 to -25 degrees Celsius. while our freezers are only up to -10 degrees Celsius. These lab freezers have to be kept locked to maintain temperature and they also have an LCD display with the temperature reading and this is for the purpose of preventing the opening of the lab freezer to check temperature.

You will find different types of lab freezers for different purposes. There are freezers that can really reach very low temperatures and can store thousands of sample using freezer racks. There is another super low lab freezer reaching the temperatures of -150 degrees Celsius without using liquid nitrogen.

Lab freezers are also used for storing flammable materials. Volatile materials can be stored in specially designed freezers. If you are freezing critical biological or life science materials then the freezer should not only comply with OSHA standards but also have alarms, monitors and back up performance features.

There is also a freezer call the blood bank freezer used to store blood and plasma. You cannot use an ordinary refrigerator for this purpose because you cannot properly maintain the balance of temperature when the doors are opened. Since blood has a very short shelf life, blood bank freezers are durable and require little maintenance.
