B065 ROTOVAPOR, ROTARY EVAPORATION APPARATUS

Category:

STANDARDS: EN 12697-3 | ASTM D5404
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.
