Autoclave vs. Sterilizer — What's the Difference?
An autoclave is a machine that uses steam under pressure to kill harmful bacteria, viruses, and spores, while a sterilizer is a general term for any equipment or process that eliminates all forms of life and other biological agents.

Key Differences
Autoclave is a specific type of equipment that uses steam under pressure to achieve sterilization. It is especially prominent in medical and laboratory environments. On the other hand, a sterilizer refers to any equipment or method that kills or removes all forms of life, including transmissible agents like bacteria, viruses, and spores.
The concept behind an autoclave is to expose each item to direct steam contact at a controlled temperature and pressure for a specified amount of time. The key variables for effective sterilization using an autoclave include temperature, pressure, and time. In contrast, a sterilizer can utilize various methods, including heat, chemicals, irradiation, high pressure, or filtration, to achieve its objective.
When professionals in the medical field refer to an autoclave, they often mean a steam-based sterilization unit that is crucial for ensuring surgical instruments and other tools are free of living organisms. However, when they mention a sterilizer, it could mean a myriad of devices, including an autoclave, or methods meant for the same purpose - eliminating biological contaminants.
It's worth noting that while all autoclaves are sterilizers, not all sterilizers are autoclaves. An autoclave specifically uses steam to kill harmful agents, while sterilizers have various modalities at their disposal.
Autoclave operation requires meticulous attention to procedural standards and regular maintenance to ensure its efficacy. Sterilizers, depending on their type, might have different protocols and operational standards to ensure optimal performance.

Autoclave
A device used for sterilizing objects by exposing them to steam at above atmospheric pressure (and thus at a temperature above the normal boiling point of water). It consists of a closed chamber able to withstand internal pressure, and a means of passing superheated steam into the chamber. Autoclaves are made in various sizes, and are much used in hospitals and research laboratories to render instruments and equipment sterile.
Sterilizer
A device used to sterilize, killing pathogens by means such as heat, UV light, chemicals, etc.
The hospital was in trouble when the sterilizer broke; they almost had to shut down the operating room.
Autoclave
A device for heating substances above their boiling point; used to manufacture chemicals or to sterilize surgical instruments
Sterilizer
One that sterilizes anything; specif., an apparatus for sterilizing equipment or an organic fluid.
Autoclave
