Questions About Equipment You Must Know the Answers To

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 specially designed to store delicate materials for a long period of time. Furthermore, laboratory refrigerators are able to accurately regulate their temperatures so that they can store materials that require specific 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 uses up far less space than the chest laboratory refrigerator, and its storage volume is not sacrificed. However, chest laboratory refrigerators are more effective in maintaining cool temperatures because they are designed in a way that they retain cool air more efficiently when compared with 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.
Why No One Talks About Cabinets Anymore
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 effectiveness of laboratory refrigerators regardless of what kind it is, thus it is best to manage room temperature below 45 degrees Celsius. Room pressure can also impact laboratory refrigerators due to the fact that high room pressures can make laboratory refrigerators wasteful, consequently it is advisable to encourage good air circulation.

It is also crucial that you remember that laboratory refrigerators give off heat when it is utilized, the same as normal refrigerators , therefore it is best not to cram an area with great number of laboratory refrigerators to be able to elude raising the temperature of the room. The design of laboratory refrigerators prevent it from being auto defrosted because auto defrosting can destroy biological samples. On top of that, there are laboratory refrigerators that are designed to retain volatile materials solely and these refrigerators are CFC free and can seal and insulate its contents from the outside environment and these refrigerators can also stand up to minute 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.
