What is an autoclave?

How does it work?

How do I disinfect with an autoclave?

First, what is an autoclave? Well, it has to do with pressure. There is a steam-heated vessel used for the purpose of sterilizing medical and dental instruments. An autoclave primarily consists of a chamber, a piston, a pressure gauge and a safety and exit valves. A liquid is used in the chamber to maintain the right pressure. The chamber also contains instruments that need to be sterilized by a mild amount of steam that is higher than the boiling point of water.

The process of sterilization by means of an autoclave is achieved by continuously cycling temperature and pressure. How does an autoclave work?

It works in the following manner:

The autoclave is turned on and heated to the correct temperature.

This is done by adding a chemical indicator to the chamber.

Moreover, steam is added within the chamber.

The pressure is kept constant by means of a control device.

During the cycle, pressure and temperature are cycled.

During pressure cycling, the instrument are exposed to temperatures. The cycle continues until the pressure gauge indicates that maximum pressure has been attained. Then, the exit valve opens and the steam is released.

Frequently Asked Questions (FAQ)

What is the best autoclave?

Autoclaves are essentially the same regardless of brand and price point with only a few variations based on the needs of the user.

Dry steam sterilizers like the Aesculap Elite and the 18W HACCP used in healthcare are more powerful equipment designed to work hard all day, every day. On the other end of the scale are the countertop models like the Steril-Gem Junior which are designed to give the best sterilization that a home user may want when sterilizing products in a small kitchen or bedroom.

Why is an autoclave the most effective sterilizer?

An autoclave is a specially designed metal cylinder that is used to sterilize instruments, surgical equipment and many other items. They are able to do this through the use of steam and pressure.

An autoclave uses high temperature, high pressure steam to eliminate microorganisms, microorganisms which would otherwise cause infection. This process is called sterilization.

Here are a few other things to consider about autoclaves: An autoclave sterilizes items at 2-12 times the temperature of a traditional oven. An autoclave sterilizes items at 15-25 times the pressure of a normal kitchen pressure cooker ‡ Because of this, an autoclave will work with any instrument or object regardless of their size.

What is class B autoclave?

Class B autoclave performs better tests and is safer than class A. The standard test has a safety factor in it that requires the Pressure-Hold test to be performed at a temperature of 250 degrees for 15 minutes. Thus in class A the pressure is allowed to be reduced during the 15 minutes to 1 pound per square inch above the rating of that particular sterilizer. Thus so long as the pressure is kept at this pressure, there is no chance of the ¼” head connection failing. As the temperature is much higher a class B autoclave will pressurize to 5 Pounds per square inch. These are very desirable for high volume industrial use e.g. medical facilities.

How do you choose an autoclave?

An autoclave is a fairly specialized piece of medical equipment, but it’s always worth spending a little extra time to choose the best autoclave for your needs. The best autoclaves will be easier to use, more effective at sterilization, and will have excellent warranties available.

To choose the best autoclave for your needs, think about what kind of sterilization you will need and when. The easiest autoclaves to use are the most affordable, but they also tend to have the shortest warranties. Discuss the options with your medical provider and your budget to decide which of the best autoclaves for your practice is right for you.
