Geoprobe® brand Dual Tube Sampling Systems are efficient methods of collecting continuous soil cores with the added benefit of a cased hole. Our line of Dual Tube Soil Sampling Systems include: DT22, DT325, DT37, DT45, and DT60.
The DT37 sampling system by Geoprobe® is used with Geoprobe® 3.75 in. Probe Rods. The DT37 tooling collects continuous soil samples approximately 2 in. in diameter. It can be used with an optional, expendable cutting shoe to allow for the installation of a prepack well through the 3.75 in. probe rod.
