Humboldt H-4210.353, Shelby Tube, 3.5in Diameter x 30in Long
Shelby tube samplers are thin-walled, hollow steel tubes, which are driven into the ground to extract a relatively undisturbed soil sample for use in laboratory tests used to determine density, permeability, compressibility and strength.
Each tube has one end that is chamfered to form a cutting edge and the upper end includes holes for securing the tube to a drive head. Shelby tubes are useful for collecting soils that are particularly sensitive to sampling disturbance, including fine cohesive soils and clays. The tubes can also be used to transport samples back to the lab as well.
Note: Size is OD. All tubes are 16 gauge steel.
3" and 5" tubes are galvanized

The Shelby Tube, 3.5in Diameter x 30in Long, also known as the Humboldt H-4210.353, is a high-quality tool used for extracting undisturbed soil samples for laboratory testing. Designed with precision and functionality in mind, this thin-walled, hollow steel tube is a must-have for geotechnical engineers, soil scientists, and researchers.
One of the key features of the Shelby Tube is its chamfered cutting edge, which ensures that the soil sample is extracted without significant disturbance. This is particularly beneficial when working with soils that are highly sensitive to sampling disturbance, such as fine cohesive soils and clays. With the Shelby Tube, you can be confident that your soil samples will accurately represent the in-situ conditions.
The upper end of the tube is equipped with holes that facilitate easy and secure attachment to a drive head. This allows for efficient and controlled insertion of the tube into the ground. Whether you are conducting density, permeability, compressibility, or strength tests, the Shelby Tube ensures that you can extract the required soil samples with precision and ease.
Not only does the Shelby Tube excel in the field, but it also serves as a reliable transport medium for soil samples. Once the sample has been collected, it can be securely sealed within the tube for safe transportation back to the laboratory. This eliminates the risk of sample contamination and ensures that your laboratory tests yield accurate and reliable results.
It is worth noting that all Shelby Tubes are constructed with 16-gauge steel. The 3" and 5" tubes are galvanized, adding an extra layer of durability and protection against corrosion.
