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. If you will know the different types of lab freezers, there are small ones that can be placed under any counter, the regular-sized freezers and the walk-in freezers which are extremely large. 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 purposes for using these lab freezers. You can find strong serums and tissue samples, bacteria strains, samples of DNA and RNA, and protein extracts in a lab freezer. These freezers are also used to preserve organs and blood in hospitals, and to keep medicines in pharmacies. To prevent degradation of specimens, they are kept in the lab freezer t constant temperature.
Like your home refrigerator unit, there are also lab freezers that are used for general purpose. They also have shelves both in the unit and in the door, and rubber gaskets to prevent the cold from escaping, just like a home refrigerator. 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 freezers can be locked and come with an LCD temperature display so that you can keep an eye on the temperature without opening the lab freezer to check.
You will find different types of lab freezers for different purposes. One type of freezer can reach very low temperatures and consists of freezer racks that can store thousand of samples. There are freezers that does not use liquid nitrogen but can reach really low temperature levels of up to -150 degrees Celcius.
Flammable materials can also be stored in lab freezers. You can also find freezers that are specially designed for volatile materials. They meet OSHA standards but should till make certain to have alarms, monitors, and back up performance features if you are freezing critical biological or high-value life science materials.
The blood bank freezer is a important freezer product, and this is used for storing blood and plasma. Blood cannot be stored in regular freezers since the temperature cannot be maintained when the doors are opened. Since blood has a very short shelf life, blood bank freezers are durable and require little maintenance.
