What is autoclave in a lab?
An autoclave is used in medical and laboratory settings to sterilize lab equipment and waste. Autoclave sterilization works by using heat to kill microorganisms such as bacteria and spores. The heat is delivered by pressurized steam.
What are the different types of autoclaves?
When picking an autoclave, it is possible to chose between three different types: Class N, Class S and Class B.
- Class N autoclaves. Class N autoclaves are compact and they are for sterilizing simple materials.
- Class B autoclaves.
- Class S autoclaves.
What are the principles of autoclave?
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 the purpose of autoclave?
Purpose. Autoclaving, sometimes called steam sterilization, is the use of pressurized steam to kill infectious agents and denature proteins. This kind of “wet heat” is considered the most dependable method of sterilizing laboratory equipment and decontaminating biohazardous waste.
What is the importance of autoclave?
An autoclave is a device that uses steam to kill spores, harmful bacteria, fungi, and viruses on items kept inside a pressure vessel for a prescribed length of time. Maintaining a sterile work environment is a key priority for a research facility or laboratory. This makes autoclaves not only useful but indispensable.
What are the two types of autoclaves?
The two basic types of steam sterilizers (autoclaves) are the gravity displacement autoclave and the high-speed prevacuum sterilizer.
What is the pressure of autoclave?
approximately 15 pounds per square inch
Autoclaves use saturated steam under pressure of approximately 15 pounds per square inch to achieve a chamber temperature of at least 250°F (121°C) for a prescribed time—usually 30–60 minutes. In addition to proper temperature and time, prevention of entrapment of air is critical to achieving sterility.
Which air is used in autoclave?
Functionally, an Air Over-Pressure Cycle is similar to a Steam-Air-Mix Cycle in that both cycles pressurize the autoclave chamber using a combination of steam and compressed air.
