SDT45 Sonic Sampling

The Geoprobe Systems® Sonic Dual Tube 45 (SDT45) is a unique and versatile soil sampling method to advance an outer casing and an inner soil sampler simultaneously. The SDT45 sample (3.0 inch diameter) is collected in a clear PVC liner, providing a high-quality, representative sample. The 4.5-inch outer casing remains in the ground (cased hole) while the sample is retrieved with inner 2.25-inch. probe rods.

SDT45 Soil Sampling Method Applications

The system provides optional bits based upon geologic conditions (soils and rock) for more efficient sampling and recovery. The versatile SDT45 sampling method can be used for many applications including:

  • environmental sampling
  • varying types of well installations
  • cased hole applications
  • geotechnical borings
  • exploration projects of numerous types

Key Features

  • Capable of collecting samples in a clear PVC liner
  • Faster trip in and trip out time compared to 4x6
  • Use of 2.25-inch center rods results in significantly less operator fatigue
  • High-quality sample integrity
  • Provides cased hole while working in consolidated or unconsolidated material
  • Bit configurations for consolidated and unconsolidated material
