What are the main components of an autoclave?


All autoclaves, regardless of size, are similar machines with a common purpose: to sterilize the parts or equipment placed in them for the purpose of sterilization and disinfection. There are different brands, different configurations, and different parts, but they all work in a similar way, generating steam and heat to sterilize the materials placed inside. Most autoclave sterilizers have several main parts in common, although there are some nuances between them.

The following are the most important components of an autoclave:

Containers are usually made of stainless steel; Most of the machine is encased in it.

Control Panel

All Autoclave steam sterilizers have their own control panel. Of course, complex machines like autoclaves don’t have exactly the same controller interfaces as household devices. Basically, the sterilization cycle follows the method provided by autoclaving software, which initiates a multistage process.

Chamber Door

The chamber door of sterilization chamber is powered by compressed air and opened by its own gravity. When working, the chamber door is closed under the drive of the compressed air cylinder, and the high-pressure steam input from the pipeline system puts the sealing ring on the chamber door, so that the sterilization chamber is sealed with the outside world.


The chamber itself is a fundamental component of any type of autoclave. The inner chamber is used to store items that need to be sterilized.


Wrapped in the outside of the sterilization chamber, it is filled with high temperature and high pressure steam when working, which plays a heat insulation role for the sterilization chamber.

Safety Valve

Because autoclaves operate under high pressure, they should be equipped with various safety measures and strong construction. The safety valve is basically a fail-safe device that keeps the internal pressure within the safe operating threshold of the machine. If all other electronic programs fail to function properly, the user is protected from danger. Because of its important role in safety, the safety valve always needs to be inspected and tested beforehand.

Vacuum System

Most modern autoclaves are equipped with a vacuum system for pre – and post-cycle purging. Used to replace all air in the room with steam and to help dry goods by removing steam at the end of the cycle.

Steam Steam Generator

A steam generator, also called a boiler, is designed to supply steam to an autoclave in the absence of a central steam source.

Wastewater Cooling System

The effluent from the autoclave is cooled before entering the drain pipe to avoid thermal damage.
