INTRODUCTION OF ROTARY EVAPORATOR
Rotary Evaporator is essentially a thin film evaporator also called rotary vacuum evaporator.
SALIENT FEATURES OF ROTARY EVAPORATOR :
1. Universal corrosion resistance.
2. Auto controlled, digital display of rotational speed and bath temperature.
3. Digital display of process time.
4. Automatic bath lifting.
5. Automatic bath lowering in case of power failure.
6. RS-232 Interface (Optional)
7. Withstands full vacuum.
8. Ideally suited for heat sensitive material.
9. Maintenance free working - Operational reliability.
10. Available in large sizes upto 400 Litre.

CONSTRUCTION OF ROTARY EVAPORATOR:
Goel Rotary Film Evaporators are completely self contained units consisting mainly of :
1. An electrically heated SS heating bath with facility for raising and lowering the height.
2. Rotating flask of corrosion resistant borosilicate glass which is connected to drive by a coupling.
3. The drive is a hollow glass shaft which also acts a vapor off-take pipe. The drive shaft s sealed on condenser/receiver with teflon seal. Power is transmitted to the shaft by a motor driven gear with provision for varying speed.
4. Condenser/receiver arrangements are of standard design depending on the model/size.
PERFORMANCE DATA OF ROTARY EVAPORATOR :
The performance of rota-evaporator depends on various parameters such as temperature differential between bath and contents of flask, RPM, flask capacity and working pressure. An indicative comparison of boil-up of CCI4 rates for 20L, 50L and 100L is given in above figure.
