The upper container is filled with water and then with embedding-material and mixed under vacuum. After the perfect mixing the special valves, that connect the mixing pot and the flask container, are opened. The lower tank is equipped with a vibrator to allow a perfect and bubble-free filling. Several small flasks or one large flask can be filled with bubble-free embedding-material.
After the filling process and the flooding of both chambers the mixing pot is washed out over the cleaning basin.
