“If we know the site condition, we can bring the 6712DT and not sub out as much, which means more profit. I don’t have to go back to the site. I don’t have to reschedule. It reduces my limitations, and I’m booked out consistently.”

Tooling & Accessories

DT22 Soil Sampling System

Video: DT22 Soil Sampling System Overview

The Geoprobe® DT22 Soil Sampling System is a direct push system for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25- inch outside diameter probe rods. Samples are collected and retrieved within a liner that is threaded onto the leading end of a string of Geoprobe® 1.25-inch OD light-weight center rods and are inserted to the bottom of the outer casing.

3.75 in. Tooling

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.

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.

MC5 Core Sampler Soil Sampling System (LWCR)

Video: Geoprobe® Macro-Core® Center Rod

Our MC5 Soil Sampling System is a single tube, discrete or continuous system with unmatched durability. MC5 Light Weight Center Rod Soil Sampling System. The MC5 1.25-inch Center Rod System was designed for the absolute worst of the worst direct push probing conditions. “These are conditions that we normally do not recommend probing in,” according to Mike Carlin, Project Engineer, “so we developed the toughest soil sampling system in the direct push industry ... it’s a brute!” Macro-Core® is a registered trademark of Kejr, Inc., Salina, KS.

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.

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.
