Description

Technical Field

[0001] This utility model mainly relates to the field of rotary evaporator technology, specifically to a protective cover for a rotary evaporator. Background Technology

[0002] To prevent damage to the distillation flask and the pot body during use, a protective sleeve is usually installed above the pot body of the rotary evaporator. Since the pot body sizes of multiple rotary evaporators in the laboratory are different, corresponding protective sleeves are usually required for use together.

[0003] Existing patent (publication number: CN216396401U) discloses a protective sleeve for a rotary evaporator and the rotary evaporator itself. The protective sleeve includes a rubber sleeve that covers the top of the heating pan of the rotary evaporator; multiple elastic protrusions are located on the surface of the rubber sleeve that does not contact the top of the pan, and the elastic protrusions are equidistantly spaced along the circumference of the rubber sleeve. After the rotary evaporator finishes evaporation, the distillation flask needs to be disassembled. This invention effectively reduces the risk of the distillation flask breaking upon impact with the top of the heating pan of the rotary evaporator.

[0004] In the process of developing this solution, the inventors found that existing integrated protective sleeve products could not be adapted to pots of different sizes. In rotary evaporation experiments, the immersion depth of the distillation flask in the pot was different, and the existing protective sleeve structure interfered with the immersion depth of the distillation flask, causing the distillation flask to be unable to be immersed in the pot to the required depth as required by the experiment.
