Advance an outer casing and inner soil sampler simultaneously using the unique and versatile Geoprobe Systems® Sonic Dual Tube 45 (SDT45) sampling system. Collect a high-quality representative SDT45 sample (3.0 in. diameter) in a clear PVC liner. The 4.5-inch outer casing remains in the ground (cased hole) while the sample is retrieved with inner 2.25-inch probe rods. Optional bits based upon geologic conditions (soils and rock) for more efficient sampling and recovery are available. Save time and fatigue with the versatile SDT45 system for your environmental sampling, varying types of well installations, cased hole applications, geotechnical borings, and exploration projects.
