The DT37 Soil Sampling System, designed for use with 3.75-inch probe rods, uses a unique combination of the cutting shoe, sheath, and liner retainer to allow efficient recovery of samples in formations ranging from plastic clays to saturated sands. The DT37 system is designed to quickly recover samples well below the water table. Problems with liner failure or having the liner lodge in sample sheath are virtually eliminated with this system.

DT45 Soil Sampling System

The DT45 Sampling System is specifically designed for use with the Geoprobe® 3230DT. This sampler provides a cased hole while providing a 3-inch diameter core sample. The durable DT45 Sampling System uses the Geoprobe® 4.5-inch probe rods as the outer casing along with the option of using standard 1.25-inch or 2.25-inch probe rods as inner casing to pull core samples.

DT60 Soil Sampling System

Video: DT60 Soil Sampling System Overview

The DT60 sampling system is the largest dual tube system from Geoprobe®. It utilizes 6-inch OD percussion driven casing and collects a 4-inch diameter soil sample. Unlike most other sampling systems, the DT60 uses a patented split sheath which gives the user the option of not using a liner. In addition to its soil sampling capacity, the DT60 system can also be used to install 2-inch monitoring wells without driving a second tool string. That means you can collect continuous soil cores and install a 2-inch prepack or conventional well within a 6-inch borehole with no expendable points or cutting shoes – all in one shot!   

Augering with the 7822DT

Hollow Stem Augers (HSA) are commonly used to set groundwater monitoring wells for environmental and for geotechnical SPT applications. With the option of an augerhead on Geoprobe® machines you can turn hollow stem augers with the same machine you had just been using for percussion probing.

Interlocking Split Spoon Sampler

Video: Interlocking Split Spoon Overview

Engineered to be stronger, last longer, and save money and time, the patented interlocking split spoon meets ASTM Standard D1586. The finger-like design self aligns, creating a perfect fit and quicker assembly. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. Multi-lead threads require fewer turns during assembly and disassembly over conventional split spoons, speeding up each test interval. In additional to time savings, enhanced material properties and manufacturing result in greater longevity. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

SP22 Groundwater Sampler

Video: SP22-ISP Groundwater Sampler

The Screen Point 22 (SP22) Groundwater Sampler from Geoprobe Systems® was designed to keep the screen away from all percussive energy while the sampler is lowered downhole, thus extending the life of the screen. The SP22 can be used alone as a groundwater grab sampler or groundwater profiling tool, or with the DT22 Soil Sampling System. The screens can be deployed using either 1.25-inch Lightweight Center Rods or PVC riser. Designed for tough probing conditions, the screen head on the fully retrievable sampler adapts to either a stainless steel or PVC screen.

Hydraulic Liner Extruder

Video: Geoprobe® Hydraulic Liner Extruder

This tool sure makes life easier in the field. In the middle of a busy day, you don’t need the hassles associated with a stubborn, stuck liner. The Geoprobe® Hydraulic Liner Extruder is simple to use and can be adapted to most Geoprobe® machines with auxiliary hydraulics. A two-piece adapter converts the extruder assembly to accommodate larger diameter DT325 sample tubes. Using the Hydraulic Liner Extruder is simple. A Macro-Core®, DT22, DT325, or DT45 Sample Tube with the sluggish liner is threaded on to the front end of the extruder. As the hydraulic "push" is applied to the opposite end of the extruder, the liner is slowly pushed from inside the Sample Tube and out the end of the extruder. Macro-Core® is a registered trademark of Kejr, Inc., Salina, KS.

Spring Assisted Swivel Lift Cap

Video: Geoprobe® Spring Assisted Swivel Lift Cap

The Spring Assisted Swivel Lift Cap is designed to reduce operator fatigue when adding or removing sections of rods to the inner tool string. The internal springs of the pull cap bear the weight of the rod string. With minimal effort, the operator can adjust the rod string up or down when threading or unthreading the rods. The natural self-alignment of the rod string prevents tipping off center and binding of the threads.
