Rotary Evaporator-Rotovap- Vacuum Rotavap
UD technologies are manufacturer, Supplier, and exporter of Industrial and Large Scale Rotary Vacuum Evaporator from Vadodara, India, and Suppliers to Indore, Hyderabad, Chennai, Mumbai, and Ahmedabad
Rotary Film Evaporator is also known as rotavapor or rotovap or rotavap
Principle of Rotary Film evaporator
The Thin-film Evaporator principle is the most universal method, as it is an efficient and gentle way to separate liquids. The rotating flask continuously covers a large surface area with a thin film, which is ideal for rapid heat transfer. Fortuitously, the film also ensures uniform heat distribution without local heating. In Rota, vapor Forms reach the cold surface of the Condenser, and condensate is collected in the receiver. Solvent removal produces Gentle concentration . Initially, evaporating Flask needs to rotate at a slower RPM due to more volume of feed. As the evaporation proceeds and volumes in the evaporating flask are lesser, RPM requires to be increased, At the end of Concentration, RPM is required to be maximum to remove solvent from the concentrate or paste. Similarly, the temperature of the Bath is required to be increased .If the temperature of the material in the Flask is to be kept at a Minimum Temperature to stop Degradation, One can take the help of a Vacuum Controller to vary the vacuum level to keep the boiling point low.
The facility to work in this evaporator under full vacuum further facilitates evaporation at as low a temperature as possible. These features render rotary film evaporators to be ideally suited for the evaporation of heat-sensitive material. It is equally successful for the evaporation of suspension in crystallization processes drying of powder/granules etc. Evaporating flask due to rotary motion forms a thin film and the vapor rising gets condensed and collected in the receiver flask. Solvent removal causes concentration and rotary motion resulting in very less contact time with the heat transfer surface.
Our Large Evaporators are user Friendly and a Single Person can remove Hot Evaporating Flask.

UD Technologies understands your requirements for Rotary Evaporation and can supply a Customised Rotary Film Evaporator and helps in Optimising Process conditions to get fast, efficient concentration with Maximum Solvent recovery.
In pursuit to give more useful Information, we have prepared a Chart of Boiling Points at different vacuums for different Solvents. We recommend 25 deg C Higher Bath Temperature than Boiling Point and 25 Deg c Lower Temperature than Boiling Point. Considering the Limitation of Coolant Availability,it is desired to vary the vacuum level referring to coolant temperature. You can check vacuum levels at different boiling points in the Chart/Table.
