The condenser is wound with a coil 11, and the coil 11 is filled with circulating cooling liquid.

The temperature control jacket 4 serves to regulate the temperature of the collecting pipe 6 and the return pipe 3, reducing or avoiding the liquefaction return of the components evaporated from the distillation flask 2 in the return pipe 3, resulting in a reduction in distillation efficiency. When the first collecting bottle 7 is distilled, the temperature control sleeve 4 can increase the temperature of the collecting pipe 6, reduce or avoid the liquefied reflux of the components evaporated from the first collecting bottle 7 in the collecting pipe 6, and reduce the efficiency of secondary distillation.

One side of the first limiting groove 18 is provided with a limiting convex edge 20, and the limiting convex edge 20 can prop against the first sealing gasket 19 to prevent the first sealing gasket 19 from displacing.

And two ends of the sealing body are provided with a second limiting groove 21 parallel to the flange 14, a second sealing gasket 22 is arranged in the second limiting groove 21, and when the two pipe bodies 13 are pulled close to each other by the bolts 15 and locked, the second sealing gasket 22 can be abutted between the limiting groove and the flange 14 to seal again. The first sealing gasket 19 and the second sealing gasket 22 are made of polytetrafluoroethylene, and have good characteristics of corrosion resistance, ageing resistance, non-conduction and the like.
