The choice of sterilizer depends on the type of material, temperature sensitivity, load configuration, required sterilization level, and operational requirements.

How Does a Sterilizer Work?

The operating principle of a sterilizer varies according to the sterilization technology being used.

A steam sterilizer, for example, uses saturated steam under controlled pressure and temperature. Heat and moisture penetrate compatible materials and destroy microorganisms. Other sterilizers may use low-temperature chemical or hydrogen peroxide-based processes for heat-sensitive equipment.

A typical sterilization process involves:

1. Preparation – Items are cleaned and prepared for sterilization.
2. Loading – Materials are placed inside the sterilizer according to the manufacturer’s instructions.
3. Air removal or conditioning – Depending on the technology, air or other gases may be removed or the chamber may be conditioned.
4. Sterilization exposure – The load is exposed to the required sterilization agent or physical process.
5. Exhaust or removal – The sterilizing agent is removed from the chamber.
6. Drying or aeration – Some processes require drying or aeration before the items can be safely used.
7. Monitoring and verification – Physical, chemical, or biological indicators may be used to verify process performance.

Correct loading, cycle selection, monitoring, and maintenance are important for achieving consistent sterilization results.

Types of Sterilizers

Different sterilization technologies are used across healthcare and industrial environments.

Steam Sterilizer

A steam sterilizer, commonly known as an autoclave, uses high-temperature steam under pressure. It is widely used for heat- and moisture-resistant medical instruments, laboratory materials, and other compatible products.

Steam sterilization is one of the most established sterilization technologies because it is effective, reliable, and relatively cost-efficient for appropriate applications.

MarketsandMarkets reports that heat/high-temperature sterilization accounted for the largest share of the sterilization equipment market in 2025, at 45.7%. The report attributes this position in part to the widespread adoption of steam sterilization. 

Dry Heat Sterilizer

Dry heat sterilizers use hot air at controlled temperatures for a specified period. They can be useful for certain materials that can tolerate high temperatures but are not suitable for moisture-based sterilization.

Low-Temperature Sterilizer

Low-temperature sterilizers are designed for heat-sensitive medical devices and instruments. Technologies can include hydrogen peroxide, ethylene oxide, and other low-temperature processes.

The increasing complexity of medical devices is creating greater demand for sterilization methods that can treat materials that cannot tolerate conventional steam sterilization. 

Ethylene Oxide Sterilizer

Ethylene oxide, or EtO, is used for sterilizing certain heat- and moisture-sensitive medical devices. It can penetrate packaging and complex device geometries, making it suitable for applications where steam sterilization is not appropriate.

Because EtO involves a chemical sterilant, its use requires appropriate controls, validated processes, monitoring, and compliance with applicable regulations.

Hydrogen Peroxide Sterilizer
