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, DT35, DT37, DT45, and DT60.
No more empty liners! No more nasty surprises! Geoprobe Systems® has permanently fused a core catcher to the Dual Tube 22 liners. The integrated core catcher prevents soil cores from falling out of the DT22 liner during sample retrieval. It's great for sampling in areas of loose soils, especially saturated sands. By fusing the core catchers directly on to the liner it will save field time for operators and make sampling in problem soils less of a hassle.
