Rotary evaporator

Rotary evaporation apparatus for determining the resistance to hardening under the influence of heat and air. 100 g of bituminous binder is introduced into the 1000 ml rotating flask of the rotary evaporator.

When the test temperature reaches 165°C a flow of air at ambient temperature is introduced into the rotating flask. The air flow hardens the sample and the hardening effect is evaluated by measuring penetration, softening point and dynamic viscosity of the treated bituminous binder sample.

Temperature range: 20-210ºC
Power supply: 230 V | 50-60 Hz | 14400 W
