Tips for buying a rotary evaporator

The rotary evaporator is developed under the vacuum negative pressure condition by the principle of constant temperature heating and thin film evaporation. The rotary evaporator uses a stepless speed regulation to rotate the glass rotating bottle at a constant speed, and the material forms a large area uniform film on the bottle wall. Then, the rotating bottle is uniformly heated by the intelligent constant temperature water bath. Evaporation at high speed under vacuum conditions, the solvent vapor is cooled by a high efficiency glass condenser and recovered in a collection bottle. The rotary evaporator is mainly used in the laboratory, which consists of a motor, a distillation flask, a heating pot, and a condenser. The rotary evaporation apparatus is mainly used for continuously distilling a large amount of volatile solvent under reduced pressure. In this article, I will introduce you to some tips for buying a rotary evaporator.

First, before purchasing a rotary evaporator, please ask yourself the following questions:

  1. What is the amount of distillation in a rotary evaporator?
  2. What is the number of samples that need to be distilled every day?
  3. What are the expected solvents for distillation? What is the approximate boiling point of the solvent?
  4. Are these solvents flammable, explosive, toxic and harmful solvents?
  5. What are the main factors affecting the efficiency of the rotary evaporator?
  6. What are the differences and advantages of rotary evaporators compared to other types of evaporators?

These big problems are believed to have been encountered by many friends in our usual distillation process. How can I avoid these problems? Lanphan is here to share you some practical skills, you can avoid these problems from the source of the rotary evaporator. Once we have determined the experimental requirements and the type of solvent to be distilled, we can start to purchase the rotary evaporator.

  1. Defining the specifications of the rotary evaporator

The specifications of the rotary evaporator are usually differentiated by the volume of the evaporation flask, and the size of the desired evaporation flask depends on the amount of material being evaporated. In general, 2L, 3L, 5L rotary evaporators are suitable for small-scale laboratory tests. The 5L, 10L, and 20L capacities are suitable for the pilot test. 20L, 50L capacity is suitable for pilot and production. Of course, in a special case, the volume of the evaporation flask can be enlarged by means of a continuous feed tube, so that a continuous distillation amount can be expanded.

  1. Identify the required distillation tasks for the rotary evaporator

Distillation efficiency is critical. The distillation efficiency of a rotary evaporator is the factor that determines the number of samples that can be distilled per day. The higher the distillation efficiency in the case of the same solvent, the greater the number of samples distilled. If the amount of sample is large, the distillation efficiency is much more thoughtful.
