What is a Rotary Vacuum Evaporator?
A rotary vacuum evaporator, commonly known as a rotary evaporator or rotovap, is a vital lab apparatus used for the vacuum evaporation of liquids. This device lowers the boiling point of solvents by applying a vacuum, enabling efficient and gentle removal of solvents from samples at low temperatures.
Also known as a rotary thin film evaporator, it consists of a rotating flask, water or oil bath, vacuum pump, condenser, and vacuum controller for rotary evaporator operations. It’s especially essential in chemical, pharmaceutical, and food industries where precision is paramount.
This method is widely used in chemistry, pharmaceuticals, biotechnology, and food industries for:
Solvent removal and recovery
Sample concentration
Recrystallization
Extraction and purification
Drying of powder or solids
Vacuum evaporation of water and other solvents
Preparation of vacuum evaporated salt
Working of Rotary Evaporator:
A rotary vacuum evaporator operates on the principle of creating a thin film through the rotation of a flask, ensuring maximum surface area for rapid and efficient heat transfer. This rotating action allows uniform heating without the risk of local overheating, which is critical for processing heat sensitive materials.
The application of a vacuum for rotary evaporator use significantly lowers the boiling point of solvents, facilitating vacuum evaporation at reduced temperatures. This minimizes thermal decomposition and shortens residence time, two factors that make the vacuum rotary evaporator ideal for delicate compounds.
Thanks to its versatility, the rotary film evaporator is well-suited not only for solvent recovery and vacuum evaporation of water but also for drying powders, granules, and crystallization processes. Whether in a laboratory vacuum evaporator setup or an industrial vacuum evaporator plant, this equipment delivers high-performance results.
Goel Rotary Film Evaporator (GRFE) is widely recognized across laboratories, research facilities, chemical processing, pharmaceutical, and biotech industries. Its design supports scalability from benchtop vacuum evaporator lab models to industrial wastewater vacuum evaporator systems.
Introduction of Rotary Vacuum Evaporator:
Rotary Evaporator, also known as a rotary vacuum evaporator, is essentially a thin film evaporator.
Salient Features of Goel Rotary Vacuum Evaporator:

8. Exceptional performance with heat sensitive and volatile substances.
9. Maintenance-free operation ensures long-term operational reliability.
10. Available in large-volume capacities, up to 400 liters, suitable for a vacuum evaporator for wastewater and industrial use.
Construction of Rotary Vacuum Evaporator:
Goel Rotary Thin Film Evaporators are fully self contained units, primarily comprising the following components:
1. Electrically heated stainless steel (SS) bath with precision controls and adjustable height mechanism.
2. Rotating flask made from durable borosilicate glass, resistant to chemical corrosion and ideal for thin film generation.
3. A motor driven hollow glass shaft, which also functions as a vapor outlet pipe. This shaft is sealed with high-quality Teflon and connected to a vacuum controller for rotary evaporator systems.
4. Condenser and receiver assemblies, crafted based on the evaporator’s size and model specifications, ensure effective vapor condensation and collection.
The equipment is compatible with standard vacuum pumps for rotary evaporator setups, allowing optimal performance across a range of pressures and temperatures.
Performance Data of Rotary Vacuum Evaporator:
The efficiency of a rotary vacuum evaporator is influenced by factors such as bath temperature, rotation speed (RPM), flask volume, and vacuum evaporator design. These parameters directly impact the evaporation rate, particularly for solvents like CCl₄.
In general, larger capacity models (e.g., 20L, 50L, 100L) demonstrate increased boil-up rates under identical conditions due to their larger surface area and optimized vacuum evaporation system. The GRFE series supports a wide range of solvent recovery, low temperature vacuum evaporation, and vacuum thermal evaporation technique applications.

Rotary Vacuum Evaporator Working Principle
The rotary vacuum evaporator working principle is based on reducing atmospheric pressure using a vacuum, which lowers the boiling point of the solvent. The solution is placed in a rotating flask that increases surface area, and the heat from a bath facilitates evaporation. The vapor is then condensed and collected separately.
This vacuum thermal evaporation technique ensures gentle processing of heat-sensitive substances, making it ideal for the vacuum evaporation of water, alcohols, and other solvents in research and production.
Key Components:
1. A sample solution is placed in a rotating evaporation flask.
2. The system is evacuated using a vacuum pump for rotary evaporator, reducing the pressure inside.
3. Gentle heating is applied via a heated water or oil heating bath.
4. The solvent evaporates at a reduced temperature.
5. Vapors are condensed and collected in a separate receiver flask.
This setup ensures efficient separation while preserving sample integrity, ideal for delicate extractions.
