B065 ROTOVAPOR ROTARY EVAPORATION APPARATUS BITUMINOUS BINDERS. RESISTANCE OF HARDENING. ROTATING FLASK TEST: RFT METHOD

Category:

STANDARD: EN 12607-3
This unit is used to evaluate the hardening effect of a treated bituminous binder sample. The test is performed by putting 100 g of bituminous
binder into the rotating flask. The sample is heated at 165°C and ambient temperature air is blowed into the flask containing the binder hardening
the same. The hardening effect is evaluated according to penetration, viscosity and softening point tests.
The Rotary Evaporation Apparatus is essentially composed of:
distillation flask 1000 ml capacity rotated by a speed motor at an adjustable rate between 20 and 280 rpm, condenser, solvent recovery flask,
heated oil bath.
The angle of the rotary/distillation flask is 15°
The instrument is supplied complete with glass tubing with three way valves and transparent flexible hose for solution intake.
The Rotatory Apparatus requires a vacuum pump and a vacuum regulating system (see accessories at p. 84).
Power supply: 230V 1ph 50-60Hz
Dimensions: 500x400x500 mm
Weight: 27 kg approx.
