The Types of Autoclave

We are in need of infection control for medical purpose. People are becoming more and more concerned about controlling pathogenic microorganism via medical instruments. Controlling the contamination is very important to prevent dangerous pathogenic microorganism transfer from one person to another.

There is an instrument that is used to sterilize medical instruments from pathogenic microorganisms. The instrument is called autoclave sterilizer. There are several types of autoclave that we can find on the market. In this article I am going to explain each type.

1. Positive Pressure Displacement

This type is the improvement of downward displacement type. The steam is created within a second in separate unit (steam generator). The steam is released to the sterilization chamber to start the sterilization progress.

2. Negative Pressure Displacement

This type is one of the most recommended types of autoclave sterilizer. It is very accurate and it can achieve high sterility assurance level. The disappointing fact is that sometimes the system is too large and too expensive.

3. Downward Displacement

This unit is also called as the gravity displacement autoclave. This unit heats water that becomes steam. The steam then forces the air in the chamber to go through the drain hole. The drain hole is closed once the temperature is sufficient for the serialization process to begin.

4. Triple Vacuum Displacement

This type is similar to the negative pressure displacement type. This unit is named “triple vacuum” because there are three process of removing the air and the steam’s pulse. This unit is perfect to sterile any kind of instruments.

5. Type “N” or type “B”

There are two classifications of autoclaves. You can find type “N” or type “B”. Type “N” does not use vacuum to remove air from the chamber. Contrary, type “B” uses vacuum pump in operation.

From the classification that I have explained above, I hope that you can understand more about each type of autoclave. Understanding the type can be beneficial when you are going to get an autoclave.
