We need infection control for medical purposes. People are increasingly concerned with controlling pathogenic microorganisms through medical instruments. Contamination control is very important to prevent the dangerous transfer of pathogenic microorganisms from one person to another.
There is an instrument that is used to sterilize medical instruments from pathogenic microorganisms. The instrument is called an autoclave sterilizer. There are several types of autoclave that we can find on the market. In this article I will explain each type.
1. Positive pressure displacement
This type is the improvement of the scroll down type. Steam is created in a second in a separate unit (steam generator). Steam is released into the sterilization chamber to start the sterilization process.
2. Displacement of negative pressure
This type is one of the most recommended types of autoclave sterilizer. It is very accurate and can achieve a high level of sterility assurance. The disappointing fact is that sometimes the system is too big and too expensive.
3. Scroll down
This unit is also called a gravity displacement autoclave. This unit heats water which turns into steam. The steam then forces the air in the chamber through the drain hole. The drain hole is closed once the temperature is high enough for the serialization process to begin.
4. Triple vacuum scroll
This type is similar to the negative pressure displacement type. This unit is called “triple vacuum” because there are three processes of air removal and steam pulse. This unit is perfect for sterilizing any type of instrument.
5. Type “N” or type “B”
There are two classifications of autoclaves. You can find “N” type or “B” type. The “N” type does not use a vacuum to remove air from the chamber. In contrast, the “B” type uses a working vacuum pump.
From the classification I have explained above, I hope you can understand more about each type of autoclave. Understanding the type can be beneficial when shopping for an autoclave.
