A rotary evaporator is a device used in Chemical Laboratories for efficient and gentle removal of solvents from samples by evaporation.

The main components of a rotary evaporators are:

1. The motor unit which rotates the evaporation flask containing sample material.
2. A vapour duct which acts as an axis for sample rotation, and a vacuum tight conduit for the vapour being drawn off of the sample.
3. A vacuum system (not integral part of the equipment) to substantially reduce the pressure within the evaporator system.
4. A heated fluid (water / thermic fluid) bath to heat the sample being evaporated.
5. A condenser with double coil through which the coolant passes.
6. A condensate collecting flask at the bottom of the condenser, to collect the distilling solvent after it recondenses.
7. A mechanical or motorized mechanism to quickly lift the evaporation flask from the heating bath or lower the heating bath so that the evaporation flask does not remain in contact with bath.

The vacuum evaporators as a class function because lowering the pressure lowers the Boiling Points of component liquids in it. Generally, the component liquids of interest in applications of rotary evaporation are solvents that one desires to remove from a sample after an extraction, for instance, following a natural product isolation or a step in an organic synthesis. Use of a Rotary Evaporator, therefore allows liquid solvents to be removed without excessive heating of what are often complex and sensitive solvent solute combinations.

Advantages ofRotary Evaporators

1. The centrifugal force and the frictional force between the wall of the rotating flask and the liquid sample result in the formation of a thin of warm solvent being spread over a large surface.
2. The forces created by the rotation suppress violently, un predicted boiling/bumping.
3. Allows quick and gentle evaporation of solvents from most samples.
4. Low temperature and vacuum control also help in kerbing bumping/foaming during evaporation process.

Thin film Evaporators are vertical, Mechanically Operated Continuous Film Evaporator designed for difficult concentration, extremely heat sensitive materials wherein the unit operations like Distillation, Evaporation and Stripping can be conducted.

This technology gives the ability to remove volatile components from less volatile materials that are heat sensitive, viscous, foaming, or contain solids. It offers short residence time, thin film formation by the centrifugal force of the rotating wiper system, the speed of which, can be adjusted to the viscosity of the product to be evaporated, which increase the evaporation efficiency. This is possible by thecreation of theuniform film on the smooth heated surface of theglass body.

Of late, the demand for test and pilot plants for gentle distillation has considerably increased in Fine Chemicals, Pharmaceuticals, Foods & Beverages industry. The Constantly rising number of new products and rising world market price of raw materials are responsible for this demand.

Salient Features:

• Maximum Evaporation in Single Pass
• The Roller wiper system (fully corrosion resistant construction) makes possible to attain a homogenous mass of liquid mixture and high wiping speed maximise evaporation efficiency.
• Minimal to no degradation of thermally unstable materials.
• The Capability of Handling High Viscosities.
• High surface to volume ratio
• Higher Heat Flux due to uniform film formation
• No dry spots and no fouling.
• Easy to clean, install and maintain
• Thin- Film Evaporators are available in DN-80 X 0.15m to DN-150 X 0.5m Evaporation surface Area.
• Thin Film Evaporators can be run up to 200C Product side and 230C Jacket Side.
• Thin Film- Evaporators can be run under Jacket Pressure of 2.0 bar (g) and evaporator can be operated at the vacuum of 5mm Hg to 0.005mm Hg.
• All wetted parts that make contact with liquids or gases are made from high precision Borosilicate Glass Tube and PTFE
