Rotary Film Evaporator


Product Description

Ablaze is a leading Rotary Evaporator Manufacturer and Supplier, we offer a large capacity commercial rotary vaccum evaporator. The Ablaze Rotary Evaporator system operates under conditions of vacuum or atmosphere.

The most common form in research is the 1 Liter to 5 Liter bench-top model, whereas, in industrial chemical operations, large-scale rotary evaporator (10L to 20 Liter and 50 Liter, 100 Liter to 200 Liter) models are used in pilot plants.

Ablaze’s series of Rotary film Evaporators are designed for Pilot and industrial scale evaporation applications.

Exclusive use of superior quality Borosilicate 3.3 glass and PTFE for all components coming in contact with product ensures complete chemical resistance against almost all mediums. It is primarily used for distillation of heat sensitive and volatile components, owing to its unique construction. It can operate under full vacuum and is an essential equipment in the chemical and pharmaceutical industries.

Rotary Evaporator Working Concept

The most rapid, reliable and environmentally safe method of extracting a volatile solvent from a non-volatile sample is to provide a rotary evaporator. For a modern chemical laboratory, this is normal equipment used to evaporate the solvent under vacuum with the use of rotation and heat. 

The theory of the rotary evaporator is that the boiling points of the liquids decrease their pressure, allowing solvents to be vaporized at much lower temperatures at normal pressure than their boiling points. A vacuum system is required to complete the entire procedure, selecting an appropriate vacuum pump for your rotavap will effectively improve the efficiency of the evaporation.

At the other end, a condenser converts gas into a liquid, and lower temperatures are required. Dry ice, water or liquid nitrogen were always used to achieve a cooling effect. The evaporation vessel rotates continuously. This technique is intended to increase the fluid surface area. The centrifugal force prevents the liquid from sticking to the vessel’s inner surface, creating a larger surface area and causing faster evaporation.

Once all the solvent evaporated (or whatever is desired at this point), the vacuum is released. The rotary flask is removed from the bath and the rotation is stopped. The vacuum is used to lower the boiling temperature thus minimizing the damage to the thermolabile substance.

Rotary Evaporator Applications

  • Distillation under continuous and batch
  • Organic chemistry to remove a solvent
  • Organic synthesis
  • Solvent recycling
  • Solvent purification
  • Reflux process reactions
  • Component drying
  • Fine chemical synthesis
  • Crystallization

Industrial Applications of Rotary Evaporator is in Medical Industry, Scientific Research and Production of Chemical and Biological Products.

Laboratories need a rotary evaporator for teaching in colleges and universities for experiment processes. Its a efficient distillation units for various labouratory experiment applications like solvents  separation from extracts, standard solvent distillation, concentration of reaction mass or solutions, crystallization, etc.

The latest use of Rotary Evaporator is also seen in Cooking Industry for Molecular cooking, using molecular gastronomy science to implement the physical and chemical principles in cooking. Using a rotovap for evaporating the liquid through a non-heating method. It maintains volatile aromatic substance which is easy to lose by heating. It’s a perfect combination of modern cooking gastronomy with lab instruments.
