Centrifuge Extractor is used for the quantitative determination of bitumen in hot-mixed asphalt mixtures and pavement samples. The Reflux centrifuges are used for the determination of bitumen percentage in bituminous mixtures. All models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminium box. They are driven by an electric motor fitted with AC drive (inverter) with the double function of speed control up to 3600 r.p.m. regardless of the frequency (50 or 60 Hz) and electrical braking. The rotating unit is suspended on the base by four calibrated springs, which assure a perfect stability all over the test. The cover is precisely machined and fitted with solvent resistant gasket to avoid leakages.
The control panel includes: Start/Stop button, speed control knob.
The Centrifuge Extractor is available in two, 1500 g and 3000 g capacity models. The apparatus is supplied complete with 100 filter papers.
