In reflux extraction, a condenser tube is usually connected to a distillation flask, and the distillation flask is placed in a water bath for heating. The rate of vapor condensed back-flow in the condenser tube generally determines the number of times the leach is repeated per unit time. Generally, in the purification process, it takes a long time to perform the reflux leaching. Resulting in longer experimental time and lower efficiency.

The contact area of the spherical condensation pipe is larger than that of the straight condensation pipe, and compared with a snake-shaped condensation pipe, the manufacturing process of the spherical condensation pipe is simple, and the spherical condensation pipe can be suitable for liquids with different boiling points. However, during purification, water flow directly passes through the outer wall of the condensation inner pipe, the water flow temperature close to the outer wall of the condensation inner pipe is higher, the water flow temperature far away from the outer wall of the condensation inner pipe is lower, heat which can be taken away by water flow is less due to direct flowing of the water flow, and the condensation speed is lower. In addition, during purification, the medicine is deposited at the bottom of the reagent bottle and cannot be fully contacted with the solvent, so that the purification efficiency is low.

As shown in fig. 2, the infrared emitting device 60 is disposed on one side of the first support 11, and the infrared receiving device 61 is disposed on the other side of the first support 11. The first support 11 is made of a transparent material so as to allow light of the infrared emitting device 60 to pass through. Since the timing from the first drop of condensate is required during the experiment, the prior art is often controlled by manual monitoring. However, this method requires the experimenter to continuously watch the observation in a squatting state, which is very time-consuming. Because the existence of infrared transmitting device 60 and infrared receiving device 61, when there is the condensate low drop, can influence infrared transmitting device 60's light to cause the change of infrared receiving device 61's resistance value, infrared receiving device 61 produces the signal of telecommunication and sends to the treater, and the treater received signal controls alarm device and reports to the police, reminds the experimenter to time.
