What Is A Rotary Evaporator?

A rotary evaporator, also known as rotavap/rotovap is a common laboratory apparatus that is designed to separate solvents from reaction mixtures. Usually, this apparatus incorporates an efficient condenser as well as a rotary flask which aids in the separation. The reaction mixture is often heated gently under reduced pressure to facilitate faster evaporation.

Once you’ve added the mixture in the flask, it is then made to rotate continuously. This leads to a creation of a thin layer of liquid over its inner surface. The thin surface layer created provides a large surface area ratio which facilitates evaporation. To fasten the rate of evaporation, heat is applied from the lower part of the flask.

Generally, a rotary evaporator can be used for two major purposes. The first purpose is the concentration of non-volatile components in a mixture. Secondly, it can be used to extract volatile molecules from mixtures. One key difference of a rotary evaporator and the normal/standard distillation is that it can separate various compounds without altering their chemical properties.

Rotary Evaporator Parts and Functions

Usually, there are four main parts that make up the entire rotary evaporator. These include the evaporation part, the vacuum pump, the condensing parts and lastly the receiving part. Each of these parts works independently to make the whole system work as desired. The following therefore are functions of the above-mentioned parts.

Evaporation part.

In the evaporation part, there exists an evaporation flask that rotates continuously. It’s designed with a wide base area to enable faster and efficient evaporation. In addition, the evaporation flask is often made to rotate at high speeds to magnify the evaporation process.

The vacuum pump

This is another significant part of the rotary evaporator. The pump helps in removing gas from the system. Through eliminating the gas, the extracted solvents are always kept pure. More importantly, the vacuum pump also creates the vacuum medium which is needed for the separation. Usually, the vacuum environment does have two primary functions: 1) reduces the pressure within the apparatus. 2) Balances the pressure between the outside environment and the inside of the apparatus.

Condensing part

The condensing parts help in the conversion of the extracted solvents from gas to liquid. This is often facilitated by the condensing tubes. Once they are condensed, the liquid is always collected for the users.

Receiving parts

This is the final step of the working process. Immediately the liquid solvents have been condensed, they are channeled to the receiving parts. The receiving part enables the user to collect the liquid much easily.

Rotary Evaporator in Different Sizes

Rotary evaporators come in different sizes and purposes. For instance, the large scale evaporators are often designed for industrial purposes, while the small scale evaporators are for small experiments. Regardless of the size, however, all the rotary evaporators are made with high-quality glass materials to make them durable and effective.

1. 5L Rotary Evaporator

5L rotary evaporator is one of the most popular rotary evaporators out there. It has a small reactor capacity of 5L and a round-bottomed evaporator flask. This makes it an ideal option for small scale separation experiments.

It’s designed with a plastic coating to provide extra safety when using it under vacuum. The condenser unit has specially designed glass tubes that use the surface area for optimized efficiency.

2. 10L Rotary Evaporator

This is another common size of the rotary evaporator in the market. Besides having a reactor capacity of 10L, it also comes with 10 glasses. It offers an ideal size for small scale users.

3. 20L Rotary evaporator

There are several models of 20 L rotary evaporator. However, irrespective of the model, some come with a reflux divider as well as a dual receiver package. Also, some models come with mobile control panels alongside bathing systems. As if not enough, there are models that use heat transfer fluid including a mono ethylene glycol. Therefore, before you purchase this unit, it’s important that you understand its features for convenience purposes.

4. 50L Rotary Evaporators

In most cases, the 50 L rotary evaporator comes with a dual receiver and a reflux divider. In addition to this, it also comes with a mobile control and an evaporator base system, all of with vary with the power system.

This model also features a diaphragm pump system. The transfer of heat is often facilitated by evaporator fluid. Lastly, this model has a reinforced tubing system and a gum rubber.

The Applications of Rotary Evaporator

The rotary evaporators are commonly used in industries and laboratories. Among the most important application industries include medical laboratories, chemical engineering companies, and biological research units or production units. These industries use processes such as evaporation, crystallization, drying, separation, and solvent recovery process to the manufacturer or reach their final products.

Also, during experiments, let’s say in learning or research institutions, the rotary evaporators are very necessary. They are used to equip learners with information that will help them become useful in industries that require separation concepts.

The cooking industry is another sector where rotary evaporators are applied. With the advancement of technology, molecular cooking is taking shape in today’s cooking industry. Here, the rotary evaporator can be used to evaporate liquid through non-heating methods. This helps maintain the volatile aromatic substance which would otherwise be lost through surface heating. This innovation is nothing but a perfect combination of lab instruments and modern gastronomy.

Final Words

Rotary evaporators are becoming popular in chemistry and industrial environments due to their efficiency in the separation of solvents. In most cases, the rotary evaporators use both evaporation and condensation techniques to effectively separate a given mixture into its components based on their respective volatilities. Furthermore, the apparatus does come in a variety of sizes such as 5L, 10L, 20L, and 50L capacities. This makes it easy for you to select the capacity that best suits your needs and experiments. Irrespective of their size, the evaporators are often made with high-quality glasses that are not only durable but safe for use.
