A rotary evaporator, commonly known as a rotovap, is a crucial device in laboratories and industries for removing solvents from liquid mixtures.
Compared to traditional evaporation methods, a rotovap offers several significant advantages.
4 Key Advantages of Using a Rotovap
1. Speed of Solvent Removal
A rotovap is much faster at removing solvents. Typically, the process takes less than 5 minutes.
This speed is due to the rotating motion of the evaporating flask, which increases the surface area of the liquid, promoting faster evaporation.
2. Lower Operating Temperatures
A rotovap operates at lower temperatures, reducing the risk of decomposition.
By using reduced pressure, the boiling point of the solvent is lowered, allowing for evaporation at cooler temperatures. This is especially beneficial for heat-sensitive substances.
3. Energy Efficiency
Using a rotovap consumes less energy compared to boiling with a heat source.
The reduced pressure and lower temperatures required in a rotovap result in significant energy savings.
4. Versatility and Size Options
Rotovaps come in various styles and sizes to meet specific needs.
Smaller benchtop setups are ideal for testing in medical and pharmaceutical fields, while larger rotovaps are used in commercial production.
10 Steps to Operate a Rotovap Efficiently
-
Turn on the rotovap and set the bath temperature to a range of 35-45°C.
-
Turn on the chiller and set the temperature to 0-5°C.
-
Turn on the vacuum pump and set the controller to slightly above the cusp of the evaporation rate, typically around 100mbar.
-
Allow both the coil and bath to reach the set temperature while the vacuum is equalized in the system.
-
Set the vacuum approximately 15-20% lower after everything has reached temperature.
-
Slowly feed a small amount of fluid into the rotovap, matching the inlet speed to the discharge side of the rotovap.
-
Dip the vacuum down as low as possible while watching the condenser and trap to manage vapors and prevent bypassing of the upper vacuum port.
-
Continually feed liquid from a storage bottle into the rotovap and replace the bottle as needed.
-
Empty the solvent discharge ball at the bottom of the condenser as needed.
-
Only empty the evaporation flask when necessary.
