Surgical instruments with complex design, shape or construction may trap contaminants that are not removed by conventional thermal disinfection procedures, thereby posing a health risk to medical personnel and patients alike. Medical instrument steam jet cleaners such as Elmasteam, available from Tovatech, have proven effective in Central Sterile Supply Departments (CSSD) for cleaning otherwise inaccessible areas prior to thermal disinfection and sterilization.

How to Use a Flammable Ultrasonic Cleaning Solution
When parts require the use of volatile and flammable solvents to accomplish ultrasonic cleaning care must be taken to prevent staff from inhaling vapors and to avoid an explosion. This is because cavitation action tends to vaporize the solvents and create an explosive cloud above the ultrasonic cleaner tank. Read More
