An adjustable rotary evaporator

Abstract

The invention belongs to the technical field of medical equipment, and especially relates to a rotary evaporator capable of being adjusted in a lifting manner. The rotary evaporator comprises a pedestal, an evaporating flask and a cylinder. The central part of the pedestal is provided with a water bath kettle, the evaporating flask is installed in the water bath kettle, one end of the pedestal is provided with a first support used for adjusting a receiving flask to move up and down, and the other end of the pedestal is provided with a second support used for adjusting a motor to move up and down. An opening of the evaporating flask is connected with the receiving flask through a pipeline, the bottom of the evaporating flask is provided with a suction cup, and the suction cup is connected with the motor through a rotating shaft. A piston rod of the cylinder stretches into the water bath kettle from the top of the water bath kettle and presses the evaporating flask. The rotary evaporator is advantaged in that the rotary evaporator is simple in structure, and can be lifted and lowered conveniently, and the evaporating flask can be lifted and lowered at any moment as needed; the suction cup is arranged on the bottom of the evaporating flask, the suction cup cooperates with the cylinder to limit the swing amplitude of the evaporating flask, and the operation stability of the rotary evaporator is improved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a rotary evaporator that can be adjusted up and down. Background technique [0002] Rotary evaporators are often used in the concentration, drying and extraction of samples in the medical field. The evaporator is placed in a water bath and heated while rotating, so that the samples in the evaporating flask are diffused and evaporated. The evaporating flask of the existing evaporator can only be rotated during the heating reaction, but the depth of immersion in the heating liquid cannot be adjusted, and the traditional water bath adopts an open structure, which makes the heat loss too fast and affects the processing reaction efficiency. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a rotary evaporator that can be adjusted up and down, which is used to solve the problem...
