Sterilization Process

We manufacture autoclave sterilizers (high temperature and pressure steam sterilizers) and plasma sterilizers (low temperature H2O2 sterilizers) that provide consistent, high quality sterilization results. Tuttnauer’s global experience has earned it a reputation as an expert on worldwide Standards and Quality considerations. Moreover, Tuttnauer plays an active role in the European Standards Committee which engages in Standards development.
