How to make rotary evaporator your own

Making a variant of a rotatory evaporator requires technical knowledge and expertise in the field of chemistry and engineering. It is not recommended to attempt this process without proper training and experience in the design and fabrication of scientific equipment. However, here are some general guidelines that you may find helpful:


Components required:

- Flask or round bottom flask

- Evaporating flask (rotary flask)

- Condenser

- Vacuum pump

- Water bath or heating mantle

- Stirrer

- Temperature probe or thermometer


Steps to remember during the process:

1. Choose the appropriate size of the flask depending on the volume of the sample you are working with.

2. The flask is placed in the heating bath, which is filled with water or oil, depending on the temperature required for the evaporation.

3. The evaporating flask is connected to the rotary motor, which rotates the flask continuously to provide a larger surface area for the evaporation process.

4. The condenser is used to cool and condense the vapors formed during the evaporation process.

5. The vacuum pump is used to lower the pressure inside the evaporating flask, which accelerates the evaporation process.

6. The stirrer is used to ensure that the sample is uniformly heated and mixed during the evaporation process.

7. A temperature probe or thermometer is used to monitor the temperature of the sample during the evaporation process.


When making your own variant of a rotatory evaporator, it is important to ensure that all the components are compatible with each other and are designed for the purpose of evaporation. It is also essential to follow appropriate safety measures, including the use of personal protective equipment and proper handling of chemicals. 


Again, it is strongly recommended to consult with a professional with expertise in the design and fabrication of scientific equipment before attempting to make your own variant of a rotatory evaporator.
