An autoclave is a laboratory or medical machine where things are placed to be sterilized or disinfected. Remember that there are many ways to sterilize materials and cleaning is important for reasons we have learned even back in school. Everything gets contaminated with microbes at once and even air contact contaminates apparatuses. Take note further that infectious viruses and bacteria have certain ways to withstand simple ways of decontamination. In laboratories, steaming of water, for example, does not ensure a 100% decontamination. Medical facilities and emergency rooms get regular exposure to infectious agents from patients with pneumonia, tuberculosis, and other illness; therefore, instruments being used to patients get a generous supply of infectious bacteria and viruses. These cannot be killed by regular means and, in many cases, to remove these bacteria totally more efficient ways should be employed. Autoclaving is one of these procedures. It uses high-temperature water or steam that is much warmer than boiling water.

We refer to inorganic impurities as those liquefied solutes like colloidal particles and mineral salts. The particles would usually be removed in basic filtration procedure requiring reverse osmosis and activated carbon. Salts, which are dissolved as ions, stay following normal decontamination. Tap water does not taste salty but it does contain a substantial quantity of ions in it. In due course, these ions are accumulated on surfaces of glass wares and materials to form spots. In apparatuses, this crisis is considered a major concern, which so as to be avoided, intensive measures must be observed. An autoclave device wherein plain water is used will not survive long as those which uses deionized autoclave water.
