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.
The DT45 Sampling System is specifically designed for use with the Geoprobe®40 series machines. This sampler provides a cased hole while providing a 3 in. diameter core sample. The durable DT45 Sampling System uses the Geoprobe® 4.5 in. probe rods as the outer casing along with the option of using standard 1.25 in. or 2.25 in. probe rods as inner casing to pull core samples.
