Correspondingly, can you use a pressure cooker as an autoclave?
A pressure cooker works just as well as autoclaving, especially for small batches. Just like an autoclave, the pressure cooker chamber reaches temperatures high enough to kill bacteria and mold spores.
In respect to this, is autoclaving high pressure?
The autoclaves are used to sterilize equipment, tools and materials. They can be used in the chemical industry, medicine and also in the processing industry. … High-pressure autoclaves are designed for pressures far above 100 bar. The material properties must therefore be able to withstand such a load.
What are the 3 types of sterilization?
Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.
- Plasma Gas Sterilizers. …
- Autoclaves. …
- Vaporized Hydrogen Peroxide Sterilizers.
What are the 4 methods of sterilization?
4 Main Methods of Sterilization | Organisms | Microbiology
- Physical Methods: …
- Radiation Method: …
- Ultrasonic Method: …

What is autoclave principle?
An autoclave is a device that works on the principle of moist heat sterilisation, wherein saturated steam is generated under pressure in order to kill microorganisms such as bacteria, viruses, and even heat-resistant endospores from various types of instruments.
What is sterilization temperature?
The two common steam-sterilizing temperatures are 121°C (250°F) and 132°C (270°F). These temperatures (and other high temperatures)830 must be maintained for a minimal time to kill microorganisms.
What is the correct temperature for sterilization by autoclaving?
What is the disadvantage of autoclave?
Disadvantages: Moisture retention. Carbon steel can get damaged due to moisture exposure. Only stainless steel instruments and plastics which can bear the heat be sterilized.
What is the pressure in autoclave?
What temperature is used for the autoclave and why is this used?
Autoclaves are widely used for heat sterilisation and commonly use steam heated to 121–134 °C (250–273 °F) with a holding time of at least 15 minutes at 121 °C or 3 minutes at 134 °C, longer for liquids and surgical instruments packed in layers of cloth.
Why do we autoclave at 121 degree Celsius?
Temperature. The standard temperature for an autoclave is 121 degrees Celsius. … The reason for this is that simply bringing something up to the temperature of boiling water, 100 degrees Celsius (212 degrees Fahrenheit), is not sufficient to sterilize it because bacterial spores can survive this temperature.
Why pressure is used in autoclave?
Summary. Steam autoclaves use high pressure and high temperature steam to kill pathogens. In order for the steam autoclave to be effective, the materials to be sterilized must be saturated with steam. … The extra pressure brings the boiling temperature of water higher bringing about more killing power.
