Bottle roller method is used to extract bitumen from asphalt for binder determination either directly or by difference. Compact bench mounted machine, designed to rotate any size combination of two bottle simultaneously along their longitudinal axis.

Bottle rotating speeds: 30 r.p.m.
Power: 180 W

Pressure filter is required for determining the binder content in accordance with BS 598-102. Bitumen extract is filtered and poured into the pressure chamber where it is filtered under controlled pressure. Filtered material is collected from an outlet in the bottom of the chamber. To indicate the pressure value during the filtering period a pressure gauge is installed at the top of the chamber housing.
Reflux extractors are used for the quantitative determination of bitumen in hot-mixed paving mixtures and pavement samples. The bitumen content is calculated by difference from the weight of extracted aggregates, moisture content and ash from an aliquot par of the extract.

75-B0013/A: Reflux bitumen extractor, 1000 g capacity
75-B0014/A: Reflux bitumen extractor, 4000 g capacity

The apparatus consists of a two wire mesh cones with interlocking frames, a cylindrical glass jar and a water condenser with inlet/outlet tubes. The extractors have to be used with a suitable hot plate with aluminium disk for better heat distribution and filter papers,  all available for order separately.
