This equipment is mainly used for the preparation processes of alkali metals (rubidium, cesium, etc.) filling, vacuum pumping, high purity gas filling, gas chamber high temperature degassing, and water bath cooling (elevating and lowering) of special glass bubbles (atomic cells), thus achieving low temperature precipitation of elementary alkali metals. It is a dedicated equipment for the preparation of gyroscopic atomic gas chambers, mainly used in inertial navigation, aerospace, ocean-going ships, scientific research, etc.
