#### General Description:

The Tuttnauer Model 4472 EP-1V and 5596 EP-1V Autoclaves are steam sterilizers that provide onboard steam generation capability. They are designed for sterilization of heat stable medical devices; wrapped solids, hollow and porous products, as well as liquids for non-clinical applications in open or closed (but not sealed) containers. The sterilization medium is steam, which is directly introduced into the sterilization chamber. This eliminates the need to wait for water introduced into the chamber to boil and reach sterilization parameters.

#### Intended Use:

The Tuttnauer Model 4472 EP-1V and 5596 EP-1V autoclaves are intended to provide sterilization of heat stable medical devices; wrapped solids, hollow and porous products, as well as liquids for non-clinical applications in open or closed (but not sealed) containers.
