Rotary Evaporator is essentially a thin film evaporator also called rotary vacuum evaporator. Working Of Rotary Evaporator: The rotating flask continuously covers a large surface area with a thin film which is ideal for rapid heat transfer. Fortuitously, the thin film also ensures uniform heat distribution without local heating. The facility to work the unit under full vacuum further facilitates evaporation at as low temperature as possible. That is to say, both boiling point and residence time are significantly reduced. These features combined, renders rotary film evaporator to be ideally suited for evaporation of heat sensitive material. It is equally successful for evaporation of suspension in crystallization processes, drying of powder granules etc.

Glass plants and pipeline should be supported correctly. To prevent inducing undesirable stresses in the glass, support should be rigid. When supported, glass should be in compression. Generally, glass plant and equipment are supported in a rectangular tubular structure. This structure is formed of galvanised mild steel tubing with the cast iron fittings which are described in this catalogue. This type of structure provides enough flexibility for future modifications and is strong enough to support a glass unit.

These vessels are used in Circulatory Boiler System and are to be supported on a vessel holder. More nozzles can be provided on the equator on request for special requirements. Cyclones can be used for the separation of droplets and solids from gases and vapours. Cyclones are to be supportd on a vessel holder. A dip pipe should be used on the top neck.

This operation involves preferential solublising of one or more soluble constituents (solutes) of a solid mixture by a liquid solvent. The unit described here is for a semi-batch operation. The solid to be extracted is put inside a glass fiber bag and placed in an extraction vessel. Solvent from the reboiler is continuously evaporated,condensed and circulated through a reflux divider by means of piping network and valves. When desired steady concentration of solute is achieved in the solution the operation is discontinued. The solution is drained off and collected for further use. After charging fresh solid in fiber bag and solvent in reboiler, the cycle can be restarted again. Solvent Extraction units are available in vessel sizes of 10, 20, & 50L and is suitable for operation under atmospheric pressure.

Standard Units Assemblies are multi-purpose units having flexibility of utility. These units have been standardized by incorporating all basic & essential features such as heating, stirring, condensation, fractionation, cooling etc. for multi-purpose use. Therefore, though termed “Standard Units” from constructional view point they actually serve as “Flexi Units” from utility point of view. These units find use in educational institutions, R&D centers and industries. They can be conveniently and quickly modified according to specific process needs due to modular construction. Borosilicate glass offers additional benefits of universal corrosion resistance, visibility and cleanliness.

A sight glass consists of one glass pipe section, one metal frame, a pair of PTFE bushes and washers and an acrylic cover. Borosilicate pipe section is highly heat resistant, has excellent chemical resistance and has low thermal expansion. Metal frame is composed of two flanges which are welded with studs so that the stresses and vibrations of the pipeline do not transfer to the glass pipe section. Its check nut keeps the glass pipe section in compression and provides ease in replacement. PTFE bushes on both sides of glass pipe section ensures that liquid in the pipeline does not come in contact with metal frame. PTFE washers are used as gaskets while fitting the sight glass in the pipeline. Acrylic cover covers the glass pipe section and protects it from outer damages.

Rotary Film Evaporator is a very regular usage product in the R & D of chemical & Pharmaceutical industry. It is also being used nowadays for manufacturing purpose for high value pharmaceutical & specialty chemical products. The existing rotary film evaporators, which are used are with spherical evaporating flasks. What happens is when the requirement of volume for process it is practically very difficult to handle the size beyond 50 liters. Chemical reactors are cylindrical in shape with a perticular LD ratio in general, which are given for a particular reaction surface area. The cylindrical vessel has a higher surface area spherical vessel. This prompted us to think in the direction; why only spherical vessel is used when we can exploit the advantage of cylindrical shape evaporation flask in a rotary film evaporator.

For special applications, cylindrical vessels can be supplied with a jacket for heating or cooling. Jacket is sealed to the vessel with Viton 'O' ring and other sealing compositions. The seal prevents high stresses between vessel and jacket by allowing the movement flexibility between two due to thermal expansion. Glass Jacket can be used for a maximum operating pressure of 0.5 bar and a maximum o operating temperature of 130 C in jacket. The temperature difference between jacket & vessel 0 should not be exceed than120 C.

In most of the glass plants, vessels are used as reactors, receivers, separators, measuring or feed vessels. Glass Reactor are available in Spherical Shape from 5 to 500 liter and in Cylindrical Shape from 5 to 500 liter capacity. Cylindrical vessels can be supplied with metalglass jackets too. We have a variety of vessel option to choose from our standard range. Beside the manufacturing of our Standard Vessels Rectors, we specialize in producing reactors as per customer's requirement. We can fabricate the reactor as per drawing or picture.
