In 1879, French microbiologist Charles Chamberland changed the healthcare field forever. His creation of a steam sterilizer for medical and scientific applications introduced a life-changing technology to the world: the autoclave.

Flash forward to the present day, and this pressurized machine—commonly used in healthcare settings—is the primary standard method for medical instrument sterilization. But what exactly is an autoclave sterilizer, and how does it work? Let’s take a closer look at the technology behind the vessel, its innovative design, and its ultimate function. Here’s what to know about the advantages of the autoclave.

The Machine: Why Steam?

So, what is an autoclave sterilizer, and how does it work? The autoclaving process uses a well-known marvel: the boiling point of water increasing under direct high pressure. Essentially, an autoclave acts as a superior sterilization machine. Because of the pressurized steam, the device can produce heightened temperatures.

You may wonder: Why not simply use contact heat from boiling water? Consider thermal energy. An autoclave may reach greater than average temperatures with its innate pressurized heating component. Due to its thermal transference capability, steam is far more effective than air to break down and kill bacteria cells and other microorganisms. No other method can quickly and efficiently decontaminate the components of a reusable utensil, tool, or instrument.

The Function: Achieving Sterility

Thoroughly cleaning medical equipment is essential in clinical settings. As mentioned above, the main purpose of autoclaves is to remove and destroy any microbial contaminants from medical instruments during a sterilization cycle. The use of an autoclave can prevent dangerous diseases or illnesses from spreading. This dependable technique is integral for laboratories, medical centers, hospitals, and research facilities to protect health, provide quality care, and produce accurate results.

The Process: Main Stages and Features

The autoclaving process is relatively straightforward. The main consideration to keep in mind is how various types of tools must undergo sterilization for diverse durations of time at diverse temperatures. Specific instrument manufacturers typically provide guidelines for time and temperature requirements. Generally, autoclaves reach temperatures of 121 to 140°C (250 to 284°F) for up to 20 minutes.

An autoclave sterilizer functions through a determined three-phase cycle. Technicians place used tools in the chamber and close the door. After locking, a vacuum pump removes any moist air and replaces it with steam for conditioning. During the exposure phase, pumped pressure increases the temperature of the steam for the desired time to achieve successful sterilization. The final phase of the cycle depressurizes the chamber, removes steam, and allows the load to dry.
