Using 254nm ultraviolet disinfection, no ozone, no secondary pollution. Specimens are stored and discarded automatically, and no one touches them during the whole process. 3. Higher adaptability: more than 95% of the site space of medium and large hospitals can be met, and existing biochemical and immunodetection equipment of multiple hospitals can be connected, and the assembly method is more flexible.
