The Geoprobe® DT22 Soil Sampling System is a direct push soil sampler for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25 in. outside diameter probe rods. Soil sampler collects and retrieves core within a soil sample tube or liner that is threaded onto the leading end of a string of Geoprobe® 1.25 in. OD light-weight center rods and are inserted to the bottom of the outer casing.
Soil Sampler Sizes
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 tubular soil sampler.
No more “push, wiggle, wedge.” Simply push the button to remove theDT22 detent drive head, saving time and frustration – for yourself and your clients. Regardless of soil type, sampling efficiency is elevated as stranded and damaged liners are eliminated. Detent drive head can be added or removed with a simple push of the button saving time and frustration.
Soil Sampler Liner
No matter what drive head you choose, you'll be field-ready with DT22 dual punch liners. The dual punch soil sampler liner accommodates standard drive heads and detent drive heads in a single product. Available without core catcher in 48 and 60-inch lengths.
Liner with Attached Core Catcher
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. Fusing the core catchers directly on to the liner saves field time for operators and make running a tubular soil sampler in problem soils less of a hassle. Available in 36, 48, and 60-inch lengths.
Extensive testing conducted by Geoprobe® tooling engineers to improve the strength of the DT22 core catcher liners has resulted in NEW soil sampler liners which are twice as strong.
Uses 2.25 in probe rods as outer casing
Uses 1.25 in. Light Weight Center Rods for core extraction
Collect continuous soil cores through a cased probe hole confirming the security of the sample from cross contamination
Optional expendable cutting shoe for use when setting prepack monitoring wells
Optional SP22 Groundwater Sampler used in conjunction with DT22
DT22 speeds production to get borings and jobs done quicker. DT22 is easier on the helper not having to pull all the tooling and using lighter rods. It's less strenuous not having to keep pulling heavy rods out of the ground.
