The Use Of Autoclave Water In Sanitizing Medical And Laboratory Equipment
The applications of pure water seem endless and in many cases tap water is out of the question. Laboratories follow strict regulations when it comes to maintenance of sterility in the facility and of its apparatuses. The common malpractice is washing the materials using ordinary water. In hospitals, the consideration of sanitation is even more compelling. It has been a wide practice to use a special type of water for autoclave sterilizers, which would become less efficient with continued use of tap water.
Ordinary water can never be used in tissue culture purposes, for instance. This is because of its impure nature, rendering it limited for typical use. While it may be all right to water your vegetable garden using water coming from deep wells and taps, it is never recommended to use it inside controlled labs. You should not even use it to rinse your glass wares if you were to keep them polished clean.
Just what is in typical water that renders it ineffective for scientific purposes?
Water exists in nature as an effective solvent that it dissolves a lot of substances. No wonder an extremely huge percentage of water on earth comes as the salty seawater that is neither safe for drinking nor good for laundering. What about water from our taps? Tap water has undergone some series of filtration to remove too much minerals and microorganisms. However, these methods do not eliminate all the impurities and in most cases this kind of water still has dissolved salts and microorganisms. To remove these remaining impurities, further intensive methods are used.
In laboratories, use of tap water to clean apparatuses causes deposition of stains from mineral impurities. The ugly stains would usually be seen in ridges and folds of the materials and would lessen the lustrous or the polished quality of the material and this is particularly an ugly thing in glass instruments. While we could be thinking much about the aesthetic rationale behind rinsing glass wares and instruments in distilled water, this only part of the purpose. Stains in laboratory instruments affect results during testing and analysis. Chemists and laboratory scientists avoid this trouble by making sure high quality water is used in washing the apparatuses.
In microbiology, biotechnology labs and in hospitals, pure distilled water must be used in sterilization purposes. Bacteria in ordinary water could harm culture and contaminate materials, making them inappropriate for scientific use.
In medicine, equipment and materials are sterilized through autoclaving. An autoclave is a special device that uses high temperature and high pressure steam to destroy microorganisms. This equipment is widely seen in medicine, dentistry, veterinary science, and microbiology. Notice that these fields rely much on sanitation and microbe-free environment.
It may sound similar to boiling but ordinary boiling raises water temperature to 100 degrees Celsius, a temperature hot enough to kill most pathogenic microbes but not hot enough to kill certain bacteria species. An autoclave produces steam at temperatures 121 degrees or more.
Autoclave water is not any kind of water and certainly not the kind that comes out of the tap. Many laboratories utilize deionized or distilled water in the autoclave. The relatively high mineral content of ordinary water would lower the efficiency and life span of the autoclave device due to deposition of stains on the inner surfaces of the sterilizing chamber. Moreover, tap water would leave stains onto surfaces of instruments placed in the autoclave.
Deionized autoclave water efficiently cleans surfaces without leaving ugly residues, enhances the effective rinsing ability of the autoclave and prolongs the life of the device itself as well as the instruments placed inside. Also, take note that an equipment or apparatus must be cleaned or washed thoroughly first before placing it into an autoclave.
