Title:
ROTARY EVAPORATOR
Document Type and Number:
WIPO Patent Application WO/2021/253371
Kind Code:
A1
Abstract:
The present invention relates to a rotary evaporator, comprising a base, a lifting/lowering base, a distillation flask, a collecting flask, a condenser, a rotary vapor duct, and a motor. A sealed connection sleeve is provided between the rotary vapor duct and the distillation flask. One end of said sealed connection sleeve sleeves onto an end of the rotary air duct. The other end sleeves onto the opening of the distillation flask. A sealing ring is provided in the sealed connection sleeve. Said sealing ring is arranged between the end of the rotary air duct and the opening of the distillation flask. The outer side of the sealed connection sleeve is provided with a tightening sleeve that causes the end of the sealed connection sleeve to constrict. By means of arranging the sealed connection sleeve and the tightening sleeve between the rotary vapor duct and the distillation flask, the present invention can, by means of the movement of the tightening sleeve, cause the sealed connection sleeve to constrict and cause the opening of the distillation flask to adhere tightly to the opening of the rotary vapor duct, increasing the stability and the sealing function of the connection between the distillation flask and the rotary vapor duct.
