Temperature controllable electronic condensation rotary evaporator

Abstract

The invention discloses a temperature controllable electronic condensation rotary evaporator. The temperature controllable electronic condensation rotary evaporator mainly comprises a distillation flask, a thermostat water bath, a decompression pump, a receiving bottle and an electronic condenser. The electronic condenser comprises a cylindrical electronic refrigeration component, a cylindrical airflow heat radiator and a finned condensing pipe. During distillation, the cold end of the electronic refrigeration component absorbs heat temperature in the condensing pipe, thermal steam in the distillation flask contacts with the wall of the condensing pipe and fins to condense, heat of the hot end is guided out by the heat radiator, and the cold end of the electronic refrigeration component is always kept at low temperature. Since the condensing pipe is isolated from the environment temperature, cooling area is enlarged and condensing temperature is lower, condensing efficiency is improved. By adjusting input current of the electronic condenser, condensation temperature can be precisely controlled; a water-cooling condenser of an existing rotary evaporator can be replaced; the temperature controllable electronic condensation rotary evaporator is simple in structure, convenient to use, easy to manufacture and popularize and has great significance in environment protection and water saving.

Problems solved by technology

[0005] In order to change the serious waste of water resources by traditional rotary evaporators, the invention solves the problem that its water-cooled condenser is difficult to reach the required condensation temperature, so that the recovery rate of low-boiling volatile solvents is low, resulting in waste of raw materials and environmental pollution ; For distillates with different condensation temperatures, the corresponding temperature cannot be accurately controlled; Substances with different vaporization temperatures in the reaction system cannot be condensed in stages after entering the condenser; and the built-in electronic condenser is affected by the ambient temperature and the conduction process. There are many defects such as the influence produced; provide a controllable electronic condensation rotary evaporator that can isolate the outside of the condensation tube of the rotary evaporator from the ambient temperature, increase the cooling area to improve the condensation efficiency, and adjust the condensation temperature according to different fractions
