Thin Wall  "SHELBY TUBE"   Sampler

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, where by the

sampler is pressed into the undisturbed clay or silts by hydraulic force.
