Autoclave sterilization is a common method of sterilizing objects and is widely used in many healthcare, manufacturing, and laboratory settings. The process uses high-temperature, high-pressure steam to kill microorganisms. High-pressure steam generated by the Autoclave enters the chamber where different heating methods may be employed.

In most cases, objects are heated by passing them through a furnace at very high temperatures, which kills anything that might be inside or on them while passing through the furnace. Like the cooking process, heat drives a chemical reaction that eliminates all living organisms from a specific object with minimal material volume loss.

What Type of Autoclave Do I Need?

Several types of Autoclaves are available for use in various settings. While the main components of an autoclave sterilizer are common, the specific components may vary depending on the type and size of the sterilization load. The most common sterilization load is a medical instrument or specimen bag. Therefore, the Autoclave must be designed to properly sterilize these objects to allow different types of sterilization cycles. These cycles range from very short and light load to long and heavy load cycles.

The cycle type is selected based on the load and the type of load being autoclaved. For example, autoclave sterilization for bags containing medical specimens placed into a sack loaded into an Autoclave chamber requires a different cycle than an operating room instrument that needs to be sterilized before placement into an operating room tray. For this reason, most Autoclaves are available in multiple models based on their level of sophistication and the complexity of the cycle they have been designed to handle.

How does autoclaving kill bacteria?

Autoclaving kills bacteria by exposing them to high temperatures and very high pressures. In addition, the steam generated in the chamber reaches more than 100°C if necessary to sterilize the load, and only simple microorganisms can survive such severe heat treatment.

How does autoclaving kill viruses?

The Autoclave usually uses steam as a sterilizing agent for most loads. If any fluids are present in the load, the high-temperature steam can also heat these fluids, but this will depend on how great fire is created inside the chamber by the added pressure. For example, most blood samples require their temperature to be very low for their components not to be denatured or destroyed during autoclaving.

Why is High Temperature Important?

The high temperatures in an autoclave chamber kill many microorganisms. In addition, the high temperature generated by the Autoclave automatically destroys any bacteria that remain on the object after the completed cycle. These bacteria may be present on the exterior surface or inside the object’s material that needs to be sterilized. You can get many options while choosing autoclave sterilization from a global lab supply. In addition, they are offering you autoclave sterilization for sale.

High Pressure:

Autoclaving works with high pressures generated by steam in a closed chamber, exceeding 10,000 psi (pounds per square inch). This steam pressure forces all moisture out of objects, thus making them highly dry and similar to glass objects. Water or moisture can no longer exist in the warm chamber, so any leftover moisture is steam evaporated in the chamber.

In some Autoclaves, the user can add water to the steam pressure zone by injecting water into a port near the door of a gas-fired model and supplying cold tap water for a liquid-fired model. In general, it is best to use dry steam because people will not form surplus water during sterilization if no liquids are present in the load.

Time consumed by Autoclave to sterilize:

It depends on the load and physical characteristics of the object being sterilized. For example, a simple medical bag with a small amount of fluid inside may take only a few minutes to sterilize in an Autoclave completely.

Multiple cycles may be needed to completely sterilize

the load for more complex loads such as surgical instruments, packs, or specimen bags. Therefore, it is important to ensure that all items being autoclaved are free of any residual moisture or loose material before setting them in an Autoclave chamber for sterilization.

Medical Equipment Sterilization:

Medical equipment sterilization is one of the most common Autoclave uses. The equipment is placed into a sterilization chamber. Where steam is generated and passed through the equipment to kill any bacteria that may be present. Such items must be free of any residual moisture or loose material. Before being them inside and allowing them to be sterilized.

The amount of time required for autoclaving varies depending on the size and. Complexity of the autoclaved load and the type of cycle used by the Autoclave. The standard cycle in a hospital Autoclave takes between 20 and 30 minutes to sterilize a bundle of items. The total time required for the cycle will depend on the size of the load being autoclaved. Therefore, it is important for medical personnel to pre-determine the number. Of items in the load and their size before the final sterilization process begins.


Autoclaves are very useful instruments in a medical setting because they make the sterilization process more efficient, time-effective, and cost-effective. Both laboratory scientists and medical personnel can benefit from using these well-designed, quickly constructed. And fairly affordable tools that perform their functions with great precision and reliability.
