Centrifuge Binder Extractors

ASTM D2172/2172M | AASHTO T164-A | EN 12697-1 | NZTA M10
CONTROLS models comprise a removable precision-machined rotor bowl housed in a cylindrical aluminium box. They are driven by an electric motor fit with AC drive (inverter) with the double function of speed control up to 3600 r.p.m. regardless of the frequency and electrical braking.
The centrifuge can be set for the automatic speed ramp up to 3600 r.p.m. or to any intermediate speed by the front knob. A digital display monitors the frequency, which is proportional to the speed.

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 fit with solvent resistant gasket to avoid leakages.

All models are fit, for emergency use, by a hand brake system.
The control panel includes: Start/Stop button, speed control knob, and digital display.

Two capacities and two versions available:
  • Standard 1500 and 3000 g cap. (75-B2212; 75-B2312)
  • Explosion proof 1500 and 3000 g cap. (75-B2222; 75-B2322)

All centrifuges are supplied complete with 100 filter discs.
75-B0022/1: Filter discs for 1500 g cap. centrifuges. Pack of 100
75-B0023/1: Filter discs for 3000 g cap. centrifuges. Pack of 100

All centrifuges can fit different capacity spare bowls:
(1500g 75-B0022/2 and 3000g 75-B0023/2)
Gilson’s popular Centrifuge Extractors provide efficient and reliable quantitative determinations of bitumen content in hot-mix asphalt specimens.

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 precision machined and balanced inner aluminum bowl assembly quickly lifts out of the sealed housing for efficient specimen handling. The heavy cast aluminum outer cover latches securely in place and features an integral solvent dispensing cup.

Filter Paper rings prevent loss of fines during processing.

HMA-265: 248mm Centrifuge Extractor Filter Rings (Grade 923), with 64mm hole diameter.
HMA-266: 298mm Centrifuge Extractor Filter Rings (Grade 923) with 64mm hole diameter.

Standard Gilson Centrifuge Extractor is useful for applications where flammability is not a concern.
It is available as 1,500g cap. model (HM-808F) with 220V/50-60Hz electrical.

Explosion-Proof Gilson Centrifuge Extractors feature explosion-proof rated motors and safe transformers, enclosed by a rugged welded tubular steel frame.

These units have models with 1,500g cap. (HM-806F) or 3,000g cap. (HM-807F) with 220V/50-60Hz electrical.
