When sterilization is carried out by water (steam) at high pressure, the process is called moist heat sterilization, on the other hand, dry heat sterilization is carried out under dry conditions at high temperature. The best way to kill microorganisms is through “heat”, as it destroys their proteins as well as the enzymes present in them. So the sterilization (destruction or killing of microorganisms) process follows the principle of killing microorganisms by providing either wet (wet) heat or dry heat.

What is moist heat sterilization?

Moist heat sterilization is another physical method used for sterilization. As the name suggests, it uses water steam. Therefore, moist heat sterilization is carried out under humid conditions. General moist heat sterilization is carried out under high pressure and high temperature. Therefore, unlike dry heat sterilization, less time is required for sterilization.

What is dry heat sterilization?

Dry heat sterilization is one of the physical sterilization methods. It uses high temperatures under dry conditions in order to remove all forms of life from a given sample or surface. Because it only uses high temperatures, it takes more time to disinfect.

Unlike wet heat sterilization, which uses high temperature to sterilize, heated air is used to achieve the same goal. In addition, the temperature of this method is higher than that of the wet heat method. Disease-causing microorganisms are killed by a destructive oxidation process. This process helps to terminate large biological molecules such as proteins. As some of the most important components of the cell are destroyed, the organism eventually dies. But most suitable for heat resistant equipment.

What are the similarities between dry heat sterilization and wet heat sterilization?

-Dry heat sterilization and wet heat sterilization are two physical sterilization methods.

-In both methods, heating is the main method of sterilization.

-Scientists use both methods in microbiology LABS.

What is the difference between dry heat sterilization and wet heat sterilization?

Dry heat sterilization occurs under dry conditions, while wet heat sterilization occurs under wet conditions. In addition, dry heat sterilization is the use of high-temperature sterilization, while wet heat sterilization is the use of high temperature and high pressure produced by water steam sterilization. Therefore, this is the main difference between dry heat sterilization and wet heat sterilization.

In addition, another difference between dry heat sterilization and humid heat sterilization is that dry heat sterilization requires a relatively long sterilization time, while humid heat sterilization requires a relatively short sterilization time. In addition, dry heat sterilization is most used in a hot air oven, wet heat sterilization is most used in autoclaves.

Although many loads (such as custom trays) can be sterilized using wet or dry heat, steam sterilizers consume less time and energy than dry heat. For resistant spores to be killed by dry heat, the load in the dry heat sterilizer must reach 170 degrees Celsius and remain there for up to 1 hour. A steam autoclave, on the other hand, can reach 121 degrees Celsius in just 15 minutes. This is because steam is an excellent conductor of heat and is, therefore, able to penetrate loads. Therefore, the use of steam thermal sterilizers can result in significant cost savings compared to dry thermal sterilizers.

The YG-0.6 Pulse Vacuum Steam Sterilizer stands out from competitors in this field because of its ability to provide optimal air removal through high-quality pulsating vacuum pumps that remove pre – and post-sterilization air. In addition, the sterilizer uses a unique steam generator that can inject a small amount of steam into the chamber to provide rapid and efficient sterilization. Also easy to use, simple interface, powerful, able to handle any type of material/load.

Conclusion – Dry and wet heat sterilization

Dry heat sterilization and wet heat sterilization are two physical sterilization methods. Dry heat sterilization is carried out at high temperature under dry air, while wet heat sterilization is carried out at a high temperature and high pressure generated by water vapor. Therefore, this is the main difference between dry heat sterilization and wet heat sterilization. In addition, dry heat sterilization requires more time to sterilize, while wet heat sterilization requires less time to sterilize. In addition, a hot air oven is the most widely used dry heat sterilization method, while an autoclave is the most widely used wet heat sterilization method.
