Construction

Rotary Film Evaporators are completely self-contained units consisting mainly of:

An electrically heated SS heating bath with facility for raising and lowering the height.
Rotating flask of corrosion resistant borosilicate glass which is connected to drive by a coupling.
The drive is a hollow GFT glass shaft which also acts as vapor off-take pipe. The drive shaft is sealed on condenser/receiver with Teflon seal. Power is transmitted to the shaft by a motor driven gear with provision for varying speed.
Condenser/receiver arrangements are of standard design depending on the model/size.
Specialty: Mechanical Seal Arrangement and T shaft (Made from GFT) with Ceramic Seal plate which results optimum vacuum Without Breakage.

Performance Data

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 CCl4 rates for 20L, 50L and 100L is given in adjacent figure.

Optional Utility Equipment for Rotary Film Evaporator

Vacuum Pump

DIAPHRAGM PUMP (Dry Pump) Suitable For RFE 5 and 20
DryFast is the latest range of the cost effective and chemical resistant diaphragm pump from WELCH Vacuum products.

This two stage diaphragm pump would be an excellent choice for a wide range of laboratory vacuum applications like distillation, drying, concentration, filtration and aspiration etc. DryFast would be your ecological chemical resistant diaphragm pump for various lab- scientific applications. DryFast can provide turnable vacuum to <8 mbar.

Functional Benefits:

Able to support a wide of chemical applications.
Uses extra coated layers of PTFE liner for diaphragm, thus making it more robust.
Dry running operation, Eco -friendly and low maintenance.
Lightweight, durable, most suitable for 24x7 of continuous operation.
Equipped with an adjustable control valve, precise settings of the flow and vacuum is easily achieved.

Key applications:

5-20 Liter Rotary Evaporation
Vacuum Oven
Vacuum Distillation
Vacuum Network
Vacuum Concentrator
Gel Dryer
Degassing Desiccation
Aspiration
Vacuum Filtration

Oil Sealed Vacuum Pump

These are oil-immersed, Rotary vane type pumps. The rotor, with two spring loaded vanes is mounted ecentric in the stator body, as the rotor rotates, the when's sweep the crecente shape air spacer twice in each revolution. There is in built non-return valve which prevents backflow of air. Manufactured from graded material/ all moving parts are precisely machined/ ground and assembled with close tolerances. this results in increased efficiency and long trouble free operating life.

Accessories:

Moisture trip. Inlet dust filter. Vacuum gauge with regulator. trolley for small pumps.
Use oil :ENCLO-46(HP)SAE-30orequivalent,vacuumoil.
Vacuum measured by mcleod gauge at suction port of the pump.

Applications:

Distillation, dehydration and filtration processes existing electronic tubes, GLS lamps/ mercury vapor lamps and tubes, vacuum methodology, vacuum sublimation, vacuum impregnation, thin film coating, refrigerator and air conditioner servicing.
