Fits Geoprobe® DT45 dual-tube samplers — 3" OD. DT45 is the largest of the dual-tube systems: it holds a cased hole open below the water table and leaves a borehole sized to accept a 2" prepack screen or monitoring well once sampling is done. If you're running DT45, this is your liner.

An aftermarket replacement liner manufactured by Universal Plastics, a Geotech Environmental Equipment, Inc. company, from rigid clear PVC extruded in the USA. The liner captures a continuous, minimally disturbed core as the sampler is driven and retrieved — stratification is readable through the liner wall on the spot, and the sample reaches the lab intact.
