As shown in fig. 1, the utility model designs an embodiment of an anti-condensation reflux condenser pipe, in which the condenser pipe is of an integrally manufactured glass pipe structure, and the pipe body is sequentially divided into an acid adding section 1 of a single-layer pipe body, a condensing section 2 of a double-layer pipe body and a reflux section 3 of the single-layer pipe body from top to bottom.

The top end of the acid adding section 1 is provided with an acid adding grinding port 11 for adding related reagents in the experimental process, and the inside of the acid adding section is a straight-through lumen.

The cavity between the double-layer tube bodies of the condensation section 2 is a condensation cavity 22, a condensed water outlet 23 is formed in the top end of the condensation cavity 22, a condensed water inlet 24 is formed in the bottom end of the condensation cavity, and a water inlet pipe 25 is integrally formed in the outer side of the tube body in the condensed water inlet 24. The water inlet pipe 25 is bent upwards to the lower side of the condensate outlet 23 along the pipe body of the condensation section 2, and meanwhile, external threads 26 are arranged at the pipe opening parts of the condensate outlet 23 and the water inlet pipe 25 so as to improve the stability of connection with a circulating cooling water pipe.

In addition, 3 ellipsoidal buffer chambers 21 are formed by the shrinkage and expansion of the inner tube body of the condensation section 2 at intervals of tube diameter.

The bottom end of the reflux section 3 is provided with a reflux grinding port 31 for butting and digesting the bottle, and the interior of the reflux section is also a straight-through pipe cavity.
