In a modern laboratory or clinic setting, maintaining infection control and a sterile environment is a top priority. This makes autoclaves useful machines in the field of scientific research. Pre-vacuum autoclaves and post-vacuum autoclaves ensure that harmful and unwanted microorganisms are destroyed. They’re not sterilized! Pre-vacuum and post-vacuum are steps in the sterilization cycle that a sterilizer should have.

The vacuum pressure steam sterilizer achieves the purpose of sterilization by removing the cold air from the chamber of the sterilizer before sterilization (98% of the cold air can be excluded). It eliminates the cold air thoroughly, and the high temperature oxidation is relatively light. It can be used at a higher temperature (132 ~ 134°C) without increasing the damage of items. As the temperature is increased, the sterilization time can be shortened and the working efficiency can be improved.

Pre-vacuum and post-vacuum autoclaves are used when air cannot be easily removed from the sterilizing medium. For example, porous, sized items such as bedding or animal cages may require special care to disinfect. Using a vacuum ensures deeper penetration of the contents, resulting in better sterilization, as the vacuum completely removes the air inside the autoclave.

The benefits of pre vacuum autoclaves and post vacuum autoclaves include:

* Remove residual air from porous loads and packages and different types of tubes by vacuum in the first stage of the sterilization cycle.

* Pre-vacuum and post-vacuum autoclaves penetrate into the load to ensure excellent sterilization.

* Autoclaves ensure increased temperature uniformity in the chamber.

* Pre-vacuum and post-vacuum autoclaves dry the material in the gadget due to the vacuum acquired in the chamber.

The type of autoclave you need depends on your job. Pre-vacuum and post-vacuum autoclaves are highly recommended because they are fast, effective, and reliable.
