In modern laboratory research and industrial production, the rotary evaporator has become the core equipment for solvent evaporation, concentration and purification. It is not only widely used in pharmaceutical, chemical, food, biotechnology and other fields, but also plays an important role in colleges and universities and scientific research institutions. Choosing a high-performance rotary evaporator can not only improve experimental efficiency, but also ensure the safety and accuracy of operation.

Core advantages of rotary evaporator

1. Efficient evaporation, improve experimental efficiency

The rotary evaporator uses a vacuum environment to reduce the boiling point of the solvent, and increases the heating area by rotating, so that the solvent evaporates quickly and condenses and recovers. Compared with traditional evaporation methods, rotary evaporation has the advantages of fast evaporation speed, low energy consumption and high recovery rate. It is an ideal equipment for laboratory solvent recovery and purification.

2. Accurate temperature control, suitable for a variety of solvents

The high-quality rotary evaporator is equipped with an intelligent PID temperature control system, and the temperature of the heating pot can be freely adjusted between **room temperature and 180℃**, ensuring that solvents with different boiling points can evaporate stably, while avoiding excessive temperature and sample degradation.

3. Safety design to ensure stable laboratory operation

The rotary evaporator uses an explosion-proof motor and an over-temperature protection system to maintain the stability of the equipment even after long-term operation. In addition, some models have an automatic lifting function. Once the power is off or the temperature is abnormal, the evaporating flask will automatically rise to avoid sample loss.

4. Modular design to meet different experimental needs

Modern rotary evaporators support a variety of condenser configurations, such as vertical, oblique and dry condensers, to meet different types of experimental needs. In addition, vacuum pumps and cooling circulation devices can be optionally equipped to achieve low-temperature evaporation and efficient solvent recovery.

How to choose a suitable rotary evaporator?

✅ Consider experimental needs: Rotary evaporators of different capacities are suitable for experiments and production of different scales, 1L is suitable for daily experiments, 5L is suitable for routine research, and 10L and above are suitable for industrial production.

✅ Choose a suitable condensation system: If the experiment needs to deal with low-boiling point solvents, a dry condenser can be selected, while for high-boiling point solvents, a water-cooled condenser is more suitable.

✅ Pay attention to safety performance: If flammable and explosive solvents are involved, it is recommended to choose equipment with explosion-proof motors and explosion-proof electronic control systems to ensure experimental safety.

✅ Supporting vacuum and cooling systems: The vacuum pump can effectively reduce the boiling point of the solvent and improve the evaporation efficiency, while the cooling circulation device can improve the condensation effect and reduce solvent loss.
