- Model HM-808 - Centrifuge Extractors



Gilson's popular Centrifuge Extractors provide efficient and reliable quantitative determinations of bitumen content in hot-mix asphalt specimens. Models conforming to explosion-proof requirements are available with 1,500 or 3,000g capacities. A standard version with 1,500g capacity is also offered. All models offer safe, simple operation and long service life.

For each model, the precision machined and balanced inner aluminum bowl assembly quickly lifts out of the sealed housing for efficient specimen handling. Rotation speeds up to 3,600rpm are easily set using the speed control knob. The built-in electric brake stops the centrifuge in seconds when extraction is complete. The heavy cast aluminum outer cover latches securely in place and features an integral solvent dispensing cup. Paper filter rings prevent loss of fines during processing.
