Key Features

1. High quality inverter, variable frequency speed regulation, stable and reliable.

2. PTFE and rubber composite seal, can maintain a high vacuum.

3. The high recovery rate is ensured by a vertical double high efficiency condenser.

4. Rotary bottles are connected with nuts for easy loading and unloading.

5. An automatic switching device is installed between the sub-condenser and the collection bottle. The collection bottle is equipped with a piston at the bottom of the mouth, and the solvent recovery is very fast.

6. The vacuum system is equipped with a vacuum meter, and the working vacuum degree can be selected for low boiling point materials.

Types of Rotary Evaporators Available

By the number of evaporation flasks

Generally, a rotary evaporator comes with at least one evaporation flask that contains the sample to be separated.

By the type of condenser

The condensers used in rotary evaporators are typically Liebig or tubular condensers.

By the type of heater

The heater in a rotary evaporator provides the heat necessary for the evaporation process. Rotary evaporators may have a heating mantle that supports the flask or a heating bath that contains hot water or oil.

By the vacuum source

A rotary evaporator's vacuum system decreases the pressure within the apparatus, expediting the evaporation of the solvent and raising the boiling point of the liquid.

Applications

Pharmaceutical industry

The pharmaceutical industry uses large-scale rotary evaporators for drug formulation, concentration of solutions, and solvent removal.

Chemical engineering

Chemical engineering employs rotary evaporators for solvent recovery, mixture separation, and process optimization in chemical production.

Food processing

Rotary evaporators are used to extract natural flavors, essential oils, and compounds in food processing. Concentrating food additives and compound extraction achieves high-purity product yields with minimal alteration to the quality of the food components.

Environmental science

Environmental science can use rotary evaporators for extraction and concentration of pollutants, sample analysis, and trace compound identification.

FAQ

Q: How safe are rotary evaporators?

A: Rotary evaporators are generally safe to use. They are equipped with safety features such as emergency stop buttons, over-temperature protection, and vacuum break valves. Operator safety also depends on proper equipment handling, risk assessment, and safety protocol adherence.

Q: What types of rotary evaporators are there?

A: There are two main types of rotary evaporators: the single rotary evaporator and the multi-rotary evaporator. The single rotary evaporator operates under vacuum and heat to remove solvents from mixtures. The multi-rotary evaporator has several evaporating flasks connected to a common evaporation unit. It's suitable for large-scale processing.

Q: Who invented the rotary evaporator?

A: The rotary evaporator was invented by L.W. Fennely in the 1950s.

Q: Does a rotary evaporator use heat?

A: Yes. A rotary evaporator uses a heating bath to gently heat the liquid in the distillation flask. This increases the temperature of the solvent. The heat speeds up the evaporation of the solvent from the mixture.

Q: Do you provide samples? Is it free?

A: Yes, we could offer the sample. Considering the high value of our products, the sample is not free, but we will give you our best price including shipping cost.

Q: Do you have warranty?

A: Yes, we offer 1.5 years warranty for the spare part.

Q: How long is your delivery time?

A: Generally it is within 7 working days after receiving the payment if the goods are in stock. Or it is 15 working days if the goods are not in stock, depending on order quantity.

Q: What is your terms of payment?

A: Payment≤15,000USD, 100% in advance. Payment≥15,000USD, 70% T/T in advance, balance before shipment.
