Sample Ejectors

Asphalt and Soil Sample Ejectors from Karol-Warner extrude compacted asphalt and soil samples from Soil Density Molds or Marshall Molds and are available in two models:

8410 4in Sample Ejector includes a 4in Extruder Disc to extract soil or asphalt samples from 4in (102mm) molds.
8400 4in / 6in Sample Ejector includes a 6in Extruder Disc as well as a 4in Adapter Ring and Extruder Disc Set to allow for extrusion of samples from either 4 or 6in (152mm) Marshall or compaction molds.

Both asphalt/soil sample ejectors can be adapted for extrusion of smaller samples with Adapter Rings and Extruder Discs (sold separately). These accessories allow for extrusion of 2, 2.5, or 3in (51, 64, or 76mm) diameter Shelby Tube samples. The 4in Adapter Ring and Extruder Disc Set, as well as the 6in Extruder Disc, can be purchased separately as replacement items.

The sturdy three-column frame is constructed of plated steel and houses a 12,000lbf (53.4kN) capacity hand-operated hydraulic jack with 5.75in (146mm) stroke. The Extruder Discs are secured to the top of the piston for level sample ejection and two wing nuts provide a fast exchange of Adapter Rings.
