At Shiva Scientific, we understand the critical role that efficient and reliable equipment plays in your laboratory processes. Our vacuum evaporators, including the advanced rotary vacuum evaporator, are designed to meet your high standards for quality and performance.
A rotary evaporator, or a rotary vacuum evaporator, is an essential tool in chemical laboratories for efficiently and gently removing solvents from samples by evaporation. Our rotary thin film evaporators and rotary film evaporators are crafted to provide superior performance and consistent results.
What is a Vacuum Evaporator?
A Vacuum Evaporator, often called a Rotary Evaporator or Rotary Vacuum Evaporator, is an essential tool in chemical laboratories. It efficiently removes solvents from samples by applying heat and vacuum, making it a vital instrument for concentration, drying, and solvent recovery.
Working of Rotary Evaporator:
The rotating flask provides a thin vacuum over a vast surface area, perfect for rapid heat transfer.
Fortunately, the thin coating ensures consistent heat dispersion while avoiding local heating. Operating the unit under full vacuum further facilitates evaporation at as low a temperature.
That is, the boiling point and residence duration are greatly lowered. These properties, when combined, make the rotary film evaporator excellent for evaporating heat-sensitive materials.
It works equally well for evaporating solutions in crystallisation operations, drying powders and granules, etc.
Rotary Evaporator, also known as a vacuum evaporator, is widely utilised in applications ranging from small-scale laboratory setups to industrial operations.
The BORO G Rotary Film Evaporator (BRFE) is a top choice for research and production facilities, and it is extensively used in laboratories and the chemical, pharmaceutical, and biotechnological industries.

9. Durable Gearbox Assembly, encasing the motor in a robust mechanical housing.
10. Fully PU Coated for added durability and corrosion resistance.
11. Base-Mounted Unit for stability and ease of use.
12. Fully Tested and Ready for Operation!
Construction of Rotary Vacuum Evaporator:
Shiva Rotary Film Evaporators are fully self-contained units comprising:
1. An electrically heated stainless steel heating bath with adjustable height.
2. A rotating flask made of corrosion-resistant borosilicate glass is connected to the drive by a coupling.
3. A hollow glass shaft that serves as both the drive and vapor off-take pipe, sealed with a Teflon seal at the condenser/receiver. A motor-driven gear with variable speed control sends power to the shaft.
4. Standard design condenser/receiver arrangements, varying by model and size.
Performance Data of Rotary Vacuum Evaporator:
The performance of the rotary vacuum evaporator is influenced by factors such as the temperature differential between the bath and flask contents, RPM, flask capacity, and working pressure. The above figure indicates the boil-up rates of CCI4 for 20L, 50L, and 100L models.
