AI Technical Summary
Existing anti-oxidation devices in organic chemistry experiments are inefficient in terms of oxygen replacement and recycling, resulting in waste and inconvenience of protective gases.
The experimental space is adjusted by moving the piston plate up and down within a transparent enclosure and using a motor-driven screw system. Combined with the design of solenoid valves and gas pipelines, this achieves efficient oxygen replacement and recycling of protective gases.
It improves oxygen replacement efficiency, reduces waste of protective gas, enables the recycling of protective gas, and lowers experimental costs.
