Rotary Evaporator


These pilot rotary evaporators are mainly built for industrial purpose to meet the challenging needs of large laboratories. All the three models of pilot rotary evaporators RE-20, RE-50 and RE-100 come with special features for flexibility to handle it easily, good distillation performance and absolutely leak-proof.

Buoyancy System Pilot rotary evaporators RE-20, RE-50 and RE-100 are equipped with a Buoyancy System. The rotary evaporator can be handled much easier than the conventional system which is available in the market. Buoyancy system emphasizes that the motor unit is fixed with the shaft, which makes it possible to rotate it at an angle of approx 45⁰. As a result, the rotating flask will move up and down in both directions according to its content.

Sealing System For achieving a good distillation performance & careful treatment of the product, a good and long-term stable sealing system is very important. Therefore, Aditya Rotary Evaporators are equipped with a mechanical sealing system that makes it possible to distil even high boiling solvent without any problem. The sealing system consists of a chemically inert material like a special PTFE compound and borosilicate glass. Under empty conditions, the sealing system can reach an ultimate vacuum value of better than 1 mbar.

Glass Parts The glass parts of a rotary evaporator are made of high-quality borosilicate glass which is processed very precisely. All the plane surfaces etc., are ground. This ensures that the system is absolutely leak proof. The absolute maximal water pressure for the condenser should be below 2 bar.

All the other functional features of Aditya 20L / 50L / 100L Rotary Evaporators are at par with any international brand available in the market today.
