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 regula-tion 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 adjusta-ble rate of 20 to 280 rpm) - solvent recovery flask, 1000 ml capacity; condenser, heated oilbath. 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  50Hz

Dimensions: 500x400x500 mm

Weight: 27 kg approx. 

一、产品介绍：

    B065 旋转法沥青回收仪用于评估处理后的沥青粘合剂样品的硬化效果。将100克沥青粘合剂放入旋转烧瓶中进行测试。将样品加热到165℃，并将环境温度的空气吹入含有硬化剂的烧瓶中。根据渗透率，粘度和软化点测试评估硬化效果，旋转/蒸馏瓶的角度约为15°。

二、产品组成部分：

·         容量为1000毫升的蒸馏瓶。

·         变速电机，适合于在20~280rpm调节转动烧瓶。

·         冷凝器。

·         溶剂回收烧瓶，容量1000毫升。

·         加热的油浴。

  该仪器配有三通阀和透明软管的玻璃管，用于溶液的吸入旋转法沥青回收仪需要一个真空泵和一个真空调节系统。

  产品总体尺寸：500*400*500mm
