As a commonly used tool for sample preparation and solvent recovery, Rotary evaporator plays an important role in chemistry, biology, pharmacy and other fields. This paper will introduce the technical improvement and innovation of Rotary evaporator, including automatic control system, condenser design, multi-channel evaporation, etc. The introduction of these improvements and innovations not only improves the efficiency and accuracy of the experiment, but also expands its application fields.

Automation control system

Traditional Rotary evaporator usually need to manually set parameters such as rotational speed, temperature and vacuum degree, which are complex to operate and easily affected by operator skills. In recent years, with the development of automation technology, the introduction of automatic control system has become an important improvement direction of Rotary evaporator. The automatic control system can monitor and adjust the speed, temperature, and vacuum degree in real time, ensuring the stability and consistency of the experiment, and reducing operator intervention.

Condenser design

During the evaporation process, the steam generated by solvent evaporation needs to be cooled and recovered through the condenser. The traditional condenser design usually adopts a cold water circulation method, but there are problems of limited cooling effect and waste of water resources. In order to improve condensation efficiency and save resources, researchers have proposed new condenser designs, such as double-layer condensers, multi-stage condensers, and external condensers, to improve solvent recovery efficiency.

Multi-channel evaporation

The Rotary evaporator usually only has a single evaporation bottle, which limits the ability to process multiple samples or solvents at the same time. In order to improve work efficiency and sample processing capacity, researchers have developed multi-channel evaporation technology. The multi-channel evaporation system can process multiple samples simultaneously, with each sample controlled independently, greatly improving the throughput of sample processing and experimental efficiency.

Data recording and tracking

The traditional Rotary evaporator has some limitations in data recording and tracking. In order to improve the traceability of experiments and the accuracy of data, researchers have begun to introduce data recording and tracking systems. These systems can record and store experimental parameters, results, and operational steps in real-time, provide visual display of data and subsequent analysis, and provide support for monitoring and optimizing the experimental process.

Environmental protection and energy-saving technology

With the improvement of environmental awareness, energy saving and emission reduction of Rotary evaporator have become an important direction of technical improvement. Researchers are committed to developing low power consumption and high efficiency Rotary evaporator, using energy-saving motors, heat recovery, intelligent control and other technical means to reduce energy consumption and environmental impact
