Information about formaldehyde sterilization

Formaldehyde (FORM) sterilization processes are so-called low-temperature-steam-formladehyde (LTSF) sterilization processes and are standardized steam sterilization processes using temperatures between 50 and 80°C. Under these conditions instruments cannot be disinfected or sterilized. Therefore, formaldehyde is added to the sterilization process.

Compared to ethylene oxide sterilization processes formaldehyde has the advantage that it does not penetrate into plastic materials. At the end of the sterilization process formaldehyde is eroded by the steam. Since formaldehyde can be observed even in extremely low concentrations that are not toxic, you can very easily tell by the smell if the formaldehyde is completely removed from the load.

There are three different kinds of formaldehyde sterilization processes, that differ in their efficacy. Detailed information can be found in our technical information.
