Condenser pipe and distillation apparatus

Abstract

The application relates to the technical field of experimental apparatus, especially relates to a condense pipe and a distillation apparatus comprising the condense pipe. The condense pipe comprises an internal pipe and an external pipe; one end of the external pipe is provided with a connection port, which is used for being connected with a reaction vessel; the other end of the external pipe is provided with a first branch pipe communicated with the internal pipe, which is used for discharging distillation light component; the external pipe is provided with a second branch pipe, one end of the second branch pipe stretches into the external pipe and is communicated with the internal pipe, the second branch pipe stretches out of the external pipe to be communicated with air. The condense pipe provided by the application can make a reaction system communicate with the air during the cleaning after reaction, cleaning fluid in the internal pipe is enabled to flow smoothly so that the condense pipe is cleaned thoroughly, and convenience in the next use is realized.

Description

Technical field [0001] This application relates to the technical field of experimental equipment, in particular to a condenser tube and a distillation device including the condenser tube. Background technique [0002] Condensing tube is a commonly used experimental instrument to promote condensation in experiments. It is connected to the reaction vessel for condensation or reflux. It usually consists of two glass tubes, one inside and one outside. The smaller glass tube penetrates the larger glass. However, the existing inner tube of the condenser tube is generally a serpentine inner tube. Because the reaction system is isolated from the atmosphere and the pressure in the reaction vessel is relatively high, it is difficult for the cleaning liquid to flow down smoothly when cleaning the condenser tube, resulting in a serpentine shape. The condensing tube is not clean, which will affect the next use. Summary of the invention [0003] The purpose of the present application is to pro...
