An autoclave is essentially a pressure vessel that uses steam pressure as a sterilizing agent. By increasing the pressure (above atmospheric pressure) the steam can reach higher temperatures. The additional pressure increases the boiling temperature of the water. Actually, about 20 ยฐ C more. This effectively increases its heat content and its ability to kill. This comes from its latent heat of evaporation.

The latest generation of autoclaves, known as "pre-vacuum generation", adds chamber preheating, steam injection, 3 pre-vacuum phases and closed-door vacuum drying: a technological "revolution" that changes parameters in the safety of professionals and patients, which is why they are known as drying autoclaves.

Types of Autoclaves a Laboratory may need

Horizontal Autoclave

Steam sterilization is the preferred method of sterilization and works by denaturing proteins. Steam autoclaves are equipment designed to use high pressure and temperature steam to kill microorganisms. Sterilization involves the complete destruction of all microorganisms, including resistant bacteria, bacterial spores, protozoa, prions, viruses and fungi present in liquids, surfaces of materials, drugs or culture media.

The good thing about steam is that it has the ability to penetrate objects that have a cooler temperature. When the steam hits a cooler surface, it condenses in the water on that object. This effectively reduces the amount of vapor present. This negative pressure in the steam draws more steam to the cooler area. Condensation occurs whenever the temperature of the condensing surface is lower than that of the steam. This allows rapid heating of surfaces, penetration into dense materials, denaturation of proteins, and sterilization of microorganisms.

Autoclave in Operation

Actually, the drying function is a feature that some horizontal Autoclave models have, they are designed with advanced technology, which allows drying the samples or surgical instruments, after sterilizing in a fast time, providing more security and functionality with its cooling and pre-programmed functions; vacuum drying at the end of the sterilization cycle ensures better drying of hollow instruments, as well as reducing the boiling temperature, causing moisture to evaporate faster and better drying to occur.

This type of autoclaves are used to absolutely eliminate all microorganisms, resistant bacteria, bacterial spores, protozoa, prions, viruses and fungi present in liquids, surfaces of materials, medicines or cultured media, in addition to being used for the sterilization and drying of hollow instruments.
