Why autoclaving is the best method of sterilization?
Autoclaves can inactivate fungi, bacteria, spores, viruses and other microorganisms on surgical instruments such as scalpels, forceps, scissors and other metal items.
Because autoclaving sterilizes without the use of reagents and allows for the re-use of lab equipment and supplies, it is environmentally friendly..
Is Lemon a disinfectant?
The acid in lemons is antibacterial and antiseptic, and it acts as a natural bleach. The citrus smell of lemon is refreshing and invigorating. … While lemons and lemon juice can do a great job with many household chores, it is not a disinfectant.

The few complications that do occur during or following sterilization, such as infection or abscess of the wound, can generally be kept to a minimum if appropriate techniques are used and if the procedure if performed in an appropriate setting.
What are methods of sterilization?

How does autoclaving kill bacteria?
The heat that an autoclave delivers via pressurized steam kills bacteria and other microorganisms by causing the organisms’ structural proteins and enzymes to lose their shape in an irreversible way, denaturing and coagulating them and making them nonfunctional.
How many types of sterilization are there?
Common methods of sterilization include physical methods and chemical methods. Physical methods include dry heat, steam, radiation, and plasmas. Radiation encompasses a variety of types, including gamma radiation, electron beam, X-ray, ultraviolet, microwave, and white (broad spectrum) light.
What is a disadvantage of flash sterilization?
What is a primary disadvantage of flash sterilization? instruments are sterilized while unpackaged, and they are no longer sterile once removed from the sterilizer so cannot be packaged. … if the sterilizing agent does not come in contact with the item for the proper time.
What is the purpose of sterilization?
Sterilization destroys all microorganisms on the surface of an article or in a fluid to prevent disease transmission associated with the use of that item.
What are three methods of sterilization?
Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.Plasma Gas Sterilizers. … Autoclaves. … Vaporized Hydrogen Peroxide Sterilizers.
Does sterilization kill viruses?
A sterile surface/object is completely free of living microorganisms and viruses. Sterilization procedures kill all microorganisms. Methods used in sterilization procedures include heat, ethylene oxide gas, hydrogen peroxide gas, plasma, ozone, and radiation.
Which equipment is used for sterilization?
Autoclaves, clean-in-place (CIP) and sterilization-in-place (SIP) systems, dry heat sterilizers and ovens, steam sterilizers, media sterilizers, and UV chambers all work to sterilize equipment and supplies.
Why is 70 Alcohol a better disinfectant than 95 alcohol?
“Isopropyl alcohol 70 percent, or isopropyl alcohol 99 percent diluted to 70 percent with purified water, kills organisms by denaturing their proteins. A 70 percent isopropyl alcohol solution dissolves their lipids and is effective against most bacteria and fungi and many viruses.”
Who is the father of sterilization?
Joseph ListerWhen surgeon Joseph Lister died at the age of 84 on February 10, 1912, he left behind a drastic reduction in the mortality of surgical patients due to infections.
What are the 4 methods of sterilization?
Sterilization can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.
Which is the best method of sterilization?
Classical sterilization techniques using saturated steam under pressure or hot air are the most reliable and should be used whenever possible. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde).
What is purpose of autoclave?
Autoclaves are used in laboratories to sterilize equipment, instruments, and infectious waste. No one who has not received training in autoclave procedure or is not working under the supervision of an experienced autoclave worker should attempt to operate the autoclave.
What is the fastest method of sterilization?
AutoclavingAutoclaving is probably the most common, quick, and safe sterilization method. Another thermal processing method is dry heat sterilization. In dry environments, bacterial spores can withstand higher temperatures for longer.
What is the most powerful disinfectant?
