Abstract

The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator, in particular to a rotary evaporator capable of simultaneously monitoring the steam temperature in a system at multiple locations. The rotary evaporator of the present invention, which can simultaneously monitor the steam temperature in the system at multiple points, can monitor the steam temperature in the rotary evaporator by setting up thermometers in the receiving bottle and the evaporation bottle of the existing rotary evaporator at the same time. Perform multi-site real-time monitoring. The rotary evaporator of the present invention can monitor the steam temperature at the position of the condenser in the evaporation system by building a first thermometer in the receiving bottle and extending the first thermometer into the condensation chamber of the condenser; at the same time , by inserting the second thermometer into the evaporating flask from the outside, or by fixing one end of the third thermometer inside the glass shaft of the transmission body and inserting the other end into the evaporating flask, Realize the monitoring of the vapor temperature in the evaporating flask.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator, in particular to a rotary evaporator capable of simultaneously monitoring the steam temperature in a system at multiple locations. Background technique [0002] Rotary evaporator, also known as rotary evaporator, is an extraction experimental equipment for vacuum distillation and concentration of materials. It is a common laboratory equipment and is widely used in large-scale concentration, drying, extraction and recovery of samples, especially for rapid A large amount of solvent was distilled off. [0003] The currently widely used rotary evaporator is usually composed of a vacuum device, a heating device, a condensing device, a rotating device and other components. The principle of the rotary evaporator is mainly controlled by electronic equipment, so that the evaporating flask rotates at a constant speed at the most suitable speed to...
