The Centrifuge Extractor, Analog Control and Explosion Proof Motor, 1500g capacity with an explosion proof motor, is designed for efficient and reliable quantitative determinations of bitumen content in hot-mix asphalt specimens. This model conforms to explosion-proof requirements and offers safe, simple operation and long service life.
For this 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.
The Centrifuge Extractor is powered by a reliable 1/8hp DC motor equipped with an electrical braking system. Extra centrifuge bowl assemblies may be ordered for faster sample processing. Twenty-five 613 grade paper Filter Rings are included. This 1,500g model uses rings 9.75in diameter with 2.5in center holes.
Dimensions for 1,500g unit: 12x20x22in (305x508x559mm), WxDxH.
