Embodiment

[0010] 1 Rotary evaporator decompression test

[0011] In order to verify the practicability of the utility model patent, this rotary tube was selected for decompression test comparison with Shanghai Zhenjie RE-52AA rotary evaporator.

[0012] The specific implementation process: 1. After the ball mill port condensing tube rotary evaporator and the straight port rotary evaporator are respectively connected, turn on the vacuum pump button to start vacuuming. You can see that the vacuum pump instrument panel shows that the vacuum degree of the condensing tube in the vacuum rotary evaporator rises rapidly, the highest It can reach 1000. 2. Contrast test of the rotary tube: connect the upper end of the rotary tube to the ball milling port of the condenser tube, fix it with stainless steel clips, insert the lower end into the collection bottle, and fix the collection bottle to the fixed protrusion with stainless steel clips. Turn on the vacuum pump, and it can be found that the vac...

Abstract

The invention discloses a diameter converting pipe capable of converting a ball-mill-hole condenser pipe of a rotary evaporator into a straight-hole condenser pipe. The diameter converting pipe comprises a glass diameter converting pipe which is externally provided with a fixed protrusion. The diameter converting pipe is simple in structure, convenient to operate, saves the space of a laboratory, easy to be operated, saves both time and force, and is economic. With the adoption of the diameter converting pipe, the ball-mill-hole condenser pipe of the rotary evaporator can be quickly converted into the straight-hole condenser pipe, so that the loss caused by converting at the secondary concentration of concentrate can be avoided, and the extracting efficiency is raised.

Description

technical field [0001] The utility model patent relates to an experimental equipment conversion device, which can be used to convert the condensing tube at the ball mill mouth into a straight-mouthed condensing tube when the rotary evaporator is used in the laboratory, which is convenient for experimental operation. Background technique [0002] The rotary evaporator is mainly used for continuous distillation of a large amount of volatile solvents under reduced pressure. It plays a very important role in the process of organic pollutant determination and other experiments, and is an important link in the extraction of organic pollutants. Various organic pollutants from agriculture, chemical industry and other industries enter the environmental medium (water body, soil, vegetation, etc.), and are adsorbed on various environmental media through a series of physical, chemical transformation and biological utilization. Under dynamic and biological action or when the environment ...
