Know Better Medical Autoclave and How It Works
By Dewi Susanti
Charles Chamberland, a French Microbiologist, was the inventor of medical autoclave in 1879. He was the one who worked alongside Louis Pasteur, the inventor of the Pasteurization process. The main function of a medical autoclave is to pressurize aqueous solutions and then heat up them over their boiling point, which will make the solution sterilized along with anything in the solution. You should be able to heat up the water above its normal boiling point in order to create sterilization using water.
Water cannot be heated more than 100 degrees Celsius under regular conditions. Simply Further heating boils the water and will not cause the liquid to rise in temperature. The way to heating up water above its normal boiling point is by heating it up in a totally covered or sealed container. This is possible since the pressure inside the sealed container rises as the water heats up, making the waters boiling point increased because of the quantity of energy required to form steam is increasing. since air is very poor at sterilizing, then first it should be absented from the autoclave chamber.
Different methods to remove air are employed by different autoclaves. In order to remove the air from the sterilization chamber a number of autoclaves utilize a vacuum pump, while the rest use an array of pressurization and depressurization of the central chamber to generate airlessness. today a lot of different industries have made wide use autoclaves including: science, dentistry, medicine, podiatry and body piercing.
In case medical autoclave is used for medical functions the idea is to sterilize reusable equipment with the aim that viruses, bacteria, and fungi are diminished. However, protein prions including those that are closely related with CJD still can withstand the common 121 degree temperature and that means can still be active. In order to totally destroy protein prions a higher temperature is employed (usually 134 degrees Celsius) along with a longer cycle. because of the humid hot environment that is generated in the instruments of a medical autoclave made out of some formations of plastic cannot be sterilized, yet a lot of small medical instruments are currently single use eliminating this problem.
In terms of the commonest brands, there are two types of medical autoclave for small worktop that can be found in a large number of labs and dental surgeries around the world: Enigma autoclaves and Prestige medical autoclaves Generally 3 methods are available to be used to make sure that a medical autoclave has achieved the right heating temperature inside the chamber and thus, sterilization has occurred.
Some medical packaging of medical autoclave comes with a chemical indicator on it changing color once the sterilization process has taken place within the packaging. In some medical autoclave an alloy can be found that will melt when the right temperature has been achieved and in the rest ones a pH sensitive chemical can be found that will change color once the needed conditions have been reached. Moreover, the indicators of medical autoclave have pressure gauges, displayed temperature sensor, and times on the outside.
