This sampler is designed to take undisturbed samples in cohesive type soils and clays. The thin steel tube containing the sample may be removed from the sampler head and used as a container to transport the sample to the laboratory thus avoiding any damage to the sample or costly delays in operation. In practice, several replacement tubes are carried by the crew to minimize disturbance, preserve moisture, and cut down on delays in the sampling procedure. The thin wall tube is made available in either steel, galvanized, or brass and in varying lengths. This sampler is also commonly called a "Shelby" or "Chicago" thin wall sampler. The procedure for taking samples is outlined under ASTM Standard Procedures, whereby the sampler is pressed into the undisturbed clay or silts by hydraulic force.

Stainless steel tubes are now available to meet your environmental sampling requirements
