Problems solved by technology

[0003] But the distilling flask, condenser pipe, and receiving flask in the rotary evaporator of the prior art are glass products, and are mainly produced abroad, and the price is very expensive. , can not withstand the temperature above 120 degrees, and flanges of other materials are required for welding between the distillation flask, condenser tube, and receiving flask, which is easy to burst and the product rate is low, which limits the application of the rotary evaporator

Abstract

The invention discloses a quartz-based rotary evaporator which comprises a condensing tube made from a quartz material, a receiving bottle and a distilling flask. A rotating device is arranged between the distilling flask and the condensing tube and is connected with a controller, a heating device is arranged below the distilling flask, a heating bath pot or a heating cover made from a quartz material is arranged at the upper end of the heating device, the heating cover is of a double-layer structure with a jacket, and the jacket of the heating cover is provided with an electric heating element. The condensing tube, the receiving bottle, the distilling flask and the heating cover in the quartz-based rotary evaporator are all made from the quartz material, on one hand, the quartz-based rotary evaporator is resistant to high temperature and does not easily crack, and on the other hand, follow-up assembly is convenient and quick. Multiple heating modes are supported, the electric heating element can be utilized to heat the distilling flask, and the distilling flask can be also indirectly heated through a heat transfer medium.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a quartz-based rotary evaporator. Background technique [0002] The rotary evaporator is mainly used for continuous distillation of large amounts of volatile solvents under reduced pressure. Especially for the concentration of the extract and the distillation of the receiving liquid during chromatographic separation, the anti-product can be separated and purified. The principle of the rotary evaporator is vacuum distillation, that is, under reduced pressure, when the solvent is distilled, the distillation bottle rotates continuously, so that a layer of liquid film is always attached to the bottle wall, increasing the evaporation area and speeding up the evaporation rate. The basic components of a rotary evaporator are a distillation flask, a condenser tube, a circulating water vacuum pump, a receiving flask and a rotating motor. [0003] But the distilling flask, con...
