Horizontal Sample Ejector

Hydraulically driven horizontal sample ejector designed for rapid ejection of 3" (76.2mm) x 30" (762mm) thin-wall sample tubes (Shelby tubes). This product also has an adjustable slider to support multiple Shelby tube lengths. The horizontal sample ejector provides a smooth and easily controlled piston stroke providing easy and rapid handling of ejected samples. The unit’s hydraulic system accurately controls the horizontal piston’s 5600lbf (24.9kN) force to eject samples smoothly. The ejector uses 1.7gpm hydraulic pump powered by a 1hp electric motor. Hydraulic oil reservoir provides 2.5gal (9.5L) capacity. This ejector can also be used with 2 or 2.5" Shelby tube samples using the corresponding conversion kit, see Accessories below. The ejector comes with (1) sample trough to support ejected samples.

Horizontal Sample Ejector Stand

Sturdy, mobile stand accommodates horizontal sample ejector. Complete with shelf for pneumatic pump and reservoir. Large wheels provide easy maneuverability. Top allows the sample ejector to be bolted to it for added stability. Requires longer hoses (included) to reach the pump and reservoir. Some assembly is required.

Hand-Operated Sample Ejector

Designed for lab and field use to extract soil samples from 4" and 6" compaction molds, as well as 2" and 2.8" tube samples. The ejection force is generated by means of a 3-ton (27.7kN) capacity, hand-operated hydraulic jack. The cast-aluminum ejector head assembly can be positioned at different heights through the use of quick-release pins. This enables the operator to easily match the ejection travel to the height of the mold being used. Piston stroke is 7.25" (184mm).

Motorized Sample Ejector

Designed for lab and field use to extract soil samples from 4" and 6" compaction molds, as well as 2" and 2.8" tube samples. This sample ejector features the use of a 5-ton capacity, motorized hydraulic pump and ram assembly. The unit incorporates extended upright rods in order to accommodate standard 4" and 6" compaction molds, as well as 2" and 2.8" sample tubes. Piston stroke is 9.25" (184mm).

Sample Ejector, Hand-Operated

Designed for lab and field use to extract asphalt samples from either 4" or 6" compaction molds. The ejection force is generated by means of a 3-ton (27.7kN) capacity hand-operated hydraulic jack. The cast-aluminum ejector head assembly can be positioned at different heights through the use of quick release pins. This enables the operator to easily match the ejection travel to the height of the mold being used. Maximum stroke distance for this ejector is 7.25".

Sample Ejector, Motorized

This Motorized Marshall Sample Ejector features the use of a 5-ton capacity motorized hydraulic pump and ram assembly. The unit incorporates extended upright rods in order to accommodate both standard 4" or 6" asphalt compaction molds, as well as the taller gyratory compaction molds. Overall dimensions excluding pump 13"W x 6"D x 29"H (330 x 152 x 737mm).

Soil Sample Ejectors are used to safely and efficiently remove soil samples from sampling tubes without disturbing their structure. These tools are essential for maintaining sample integrity in geotechnical testing and laboratory analysis.
