Vacuum Systems For Sterilizers And Autoclaves

Sterilization is moist heat in the form of saturated steam under pressure. The purpose is to expose each item to direct steam contact at a required temperature and pressure for a specified time to destroy microorganisms that may contaminate a product or container. 

Nash utilizes vacuum in the four main types of sterilization, which are: steam sterilization, hydrogen peroxide plasma sterilization, ethylene oxide sterilization, and formaldehyde gas sterilization. Our vacuum systems optimize production with high reliability and energy efficiency. 

Formaldehyde Gas Sterilization 


Another low-temperature method for sterilization is formaldehyde gas sterilization, which is for heat-sensitive items. Formaldehyde is used as a fumigant in gaseous form. Formaldehyde sterilization is complex and less efficacious than other methods of sterilization. This technique should only be used if steam under pressure will damage the item to be sterilized and ethylene oxide is not available.

Ozone Gas Sterilization

Lastly, ozone gas sterilization sterilizes by oxidation, a process that destroys organic and inorganic matter. Ozone is an unstable gas but can be easily generated from oxygen. A 6% to 12% concentration of ozone continuously flows through the chamber. The penetration of ozone may be controlled by the vacuum in the chamber or enhanced by adding humidity. As completion of exposure time, oxygen is allowed to flow through the chamber to purge the ozone. Depending on the size of the chamber load, cycle time could be up to 60 minutes.
