ROTOVAPOR

This unit is used to recover bitumen from a solvent by minimizing the changes in the asphalt properties.
The test is performed by distilling the residue of the solution of solvent and asphalt. The rotating distillation flask is partially immersed in a heated oil bath, and the solution is subjected to high vacuum, with fine regulation of pressure (up to ± 0.1 kPa) according to EN 12697-3.
The Rotary Evaporation Apparatus is essentially composed of:
  • distillation flask 1000 ml capacity
  • motor of variable speed, (suitable to rotate the flask at an adjustable rate of 20 to 280 rpm)
  • solvent recovery flask, 1000 ml capacity; condenser, heated oil bath.
The angle of the rotary/distillation flask is 15°.
The instrument is supplied complete with glass tubing with three way valve and transparent flexible hose for solution intake.
The Rotatory Apparatus requires a vacuum pump and a vacuum regulating system (see accessories).

Power supply: 230V 1ph 50-60Hz
Dimensions: 500x400x500 mm
Weight: 27 kg approx.
