AI Technical Summary
When used in existing rotary evaporators, the decanter and heating pot are mostly open-air operations, which pose safety risks. The amount of water in the heating pot is reduced and the automatic water addition function is lacking, resulting in manual water addition, which consumes manpower and reduces the distillation efficiency.
A new rotary evaporator was designed, which covered the heating pot with a protective cover to prevent glass fragments from splashing. Through the cooperation of the floating plate and the float ball, the water flow between the connecting pipe and the heating pot is automatically controlled to realize the automatic water addition function of the heating pot. .
It effectively prevents safety hazards caused by damage to the decanter, and through the automatic water addition function, the distillation efficiency is improved, manual intervention is reduced, and human resources are saved.
