The Shelby sampler is a thin-walled soil sampling system. The system is used to sample soils that are particularly sensitive to sampling disturbance, as it has a very low wall thickness-to-sample area ratio. The sampler consists of a thin walled steel tube whose lower end is shaped to form a cutting edge.

Fieldtech Solutions is now stocking U63 and U50 Shelby Tubes and drive heads. Drive Heads are available in AW, AWJ, or NWJ box threads.
