[0002] The glass distillation device commonly used in the laboratory is equipped with a kettle body, a kettle cover, a reflux elbow, a condensing coil and other components. After the kettle body is heated, the solvent reaching the boiling point will volatilize into a gaseous state and go to the kettle cover part at the top, then enter the reflux elbow and the condensing coil in turn. The gaseous solvent entering the condensing coil will condense into a liquid state again after being cooled and then flow back to the lower part, re-entering the kettle body for a new round of distillation.
[0003] The interface connection subassembly of the traditional glass distillation device adopts a spherical concave notch for the kettle cover and a spherical convex notch for the reflux elbow, which causes the solvent condensed into a liquid state to flow into the kettle through the spherical concave notch of the kettle cover and then along the glass wall, resulting in a certain hysteresis of the secondary reaction in the kettle body. Moreover, the traditional interface connection method requires applying vacuum silicone grease at the connection part, which will enter the kettle body through the spherical concave notch of the traditional structure and contaminate the solvent in the kettle body.
[0004] To solve the above problems, the utility model provides an interface connection subassembly of a glass distillation device. UTILITY MODEL CONTENTS

[0015] Preferably, according to any one of the above solutions, the interiors of the eight connecting blocks are inserted with four fastening screws, and the exteriors of the four fastening screws are threadedly connected with a fastening block.
[0016] Preferably, according to any one of the above solutions, one side of the kettle cover is fixedly connected with an extension pipe, and the extension pipe is arranged below the connecting pipe.
[0017] The technical effect achieved by the above solution is that the condensed liquid solvent flows back to the inside of the kettle body along the extension pipe instead of along the glass wall.

[0021] 2. The traditional interface connection mode also needs to smear the vacuum silicone grease at the connection, so that the vacuum silicone grease enters the inside of the kettle body along the ball surface concave of the traditional structure to pollute the solvent in the inside of the kettle body, however, the application does not need to smear the vacuum silicone grease at the connection, and can also ensure the sealing of the interface connection assembly, thereby avoiding the pollution of the vacuum silicone grease to the solvent in the inside of the kettle body, so that the practicality of the interface connection assembly can be greatly improved.
