Gilson Reflux Extractor

Reflux Extractors are used for reflux extraction to determine asphalt content in bituminous pavement mixtures, which is the least expensive method.

Hot plates generate solvent vapor that passes around and through the sample contained in two wire mesh cones lined with filter paper. Reflux solvent condensing on the water-cooled condenser percolates through the sample repeatedly until the bitumen is extracted.

Reflux Extractors are offered in nominal capacities and include a Hot Plate, Extraction Jar, two interlocking wire Mesh Cones with bail handles, copper Condenser with water inlet/outlet tubes, Filter Paper, and Insulating Pad. Models operate on 115V, 50/60Hz or 230V, 50/60Hz.

HM-5 mdoels have a sample capacity of 1,000g.

HM-6 models have a sample capacity of 2,000g.
