Laboratory Refrigerators vs. Domestic Refrigerators
Ordinary people think that the difference between domestic refrigerators and laboratory refrigerators is just their size, however, there is more to laboratory refrigerators than its bigger size. Laboratory refrigerators are created specifically to store vulnerable materials for a long period of time. Additionally, laboratory refrigerators can perfectly manage their temperatures so that they can store materials that need particular storage temperatures.
Laboratory refrigerators are categorized into two types, namely the chest freezer and the upright freezer and the difference between the two is the space that they occupy. The upright laboratory refrigerator takes up a lot less space than the chest laboratory refrigerator, and its storage capability is not sacrificed.
Nevertheless, chest laboratory refrigerators are more effectual in sustaining cool temperatures as they are made in a way that they hold cool air more proficiently in contrast to upright refrigerators. This also applies when the refrigerator doors are open, because chest laboratory refrigerators are able to retain their temperature more effectively than upright refrigerators even when the freezer is open for long periods of time.
A Quick Overlook of Equipment – Your Cheatsheet
To make laboratory refrigerators more potent and competent at regulating temperatures, the temperature of the room in which they are kept needs to be controlled as well. High room temperatures can have an effect on the functionality of laboratory refrigerators whatever kind it is, consequently it is best to set up room temperature below 45 degrees Celsius. Room pressure can also affect laboratory refrigerators because high room pressures can make laboratory refrigerators inefficient, hence it is best to facilitate proper air circulation.
The Best Advice About Equipment I’ve Ever Written
It is also crucial that you keep in mind that laboratory refrigerators give off heat when it is being employed, the same as normal refrigerators , consequently it is best not to cram an area with way too many laboratory refrigerators to be able to prevent raising the temperature of the room. The design of laboratory refrigerators prevent it from being auto defrosted because auto defrosting can destroy biological samples. Laboratory refrigerators are also designed to efficiently store flammable and volatile materials without sacrificing safety. Furthermore, there are laboratory refrigerators that are designed to store volatile materials specifically and these refrigerators are CFC free and can seal and insulate its contents from the outside environment and these refrigerators can also withstand small explosions.
Probably the most important feature of any laboratory refrigerator is the alarm system that the company that made the refrigerator installed and programmed. These alarm systems can sense minor modifications in temperature and will caution the user correspondingly. Some laboratory refrigerators also have locks that can be accessed by a password that the user can formulate, and this is added protection for dangerous or important samples that need special handling.
