STAR offers a wide range of solutions based on evaporation in different application fields.
Application:
Batch or Continuous Operations under vacuum or atmospheric pressure.
"Evaporation of solvents containing heat sensitive materials or solids under reduced pressure.
Vacuum drying of wet solids.
Especially designed for high boiling solvents.
Degassing of liquids.
 
Principal of Rotary Evaporator
The system consists of:
Thin Film Evaporation.
Large Surface Area
Uniform transfer of heat through its glass wall to the thin film.
A wide range of evaporation flask volumes from 1 liter up to 50 liter allows finding an appropriate size of distillation performance from the Lab up to the Production Plant.

Its broad temperature range from +20¡Æ C to +180¡Æ C opens up a wide range of applications and it's modular design makes it possible to fully adapt the evaporator to your individual needs.
 
Outstanding Features
High performance sealing system.
Dual over-temperature cutout devices
manually adjustable maximum temperature control
Protection hood for the oil/water bath & rotating flask
All components are designed to suit high Vacuum
High efficiency with limited space requirements
High Distillation rates/Solvent Recover
Low Operating Temperature
High purity of distillate/Solvent
All evaporators can be upgraded for future needs
 
 
Overview of the System
A typical set up of Rotary Evaporator glassware consists of an evaporating flask, a receiving flask & a condenser. The evaporating flask holds the sample to be evaporated. Once a sample is placed in the evaporating flask, it is lowered in to a heated water bath and is rotated in the water bath. The rotation of the evaporation flask creates a thin film of sample on the inside of the glassware. Increase surface area encourages evaporation of the molecules. Heated water encourages the free flow of molecules to move toward the condenser to be collected in the receiving flask. The receiving flask collects the condensate that comes from the condenser for evaluation of the pure solvent or proper waste disposal
 
The system consists of:
Evaporating Rotating Flask - 1 no..
Sparkless Induction Electric gear motor -1 no.
Cooling Condenser - 1 no.
Receiver Flask - 2 nos.
Instrument panel includes
RPM Controller
Bath Temperature Controller
Stand
 
Construction: Rotary Film Evaporator
Stand : Rotary Film Evaporator is a completely self - contained transportable Bench-top unit.
    This stand apart from acting as a support for the Heating Bath, Rotating Flask, Drive Unit And Receiver arrangement and all the controls.
Heating Bath : Rotary Film Evaporator is supplied with an Electrically - heated Water Bath. Electrically heated Oil Bath can also be supplied (Optional) The Bath can be lowered mechanically to facilitate removal of the Rotating Flask.
Rotating Flask : The Rotating Flask is of corrosion resistant Borosilicate Glass and is Connected to the drivers by means of a quick release coupling.
