SPT Split Tube Samplers, A type of soil sampling device, used in conjunction with the Big Beaver auger drill rig and soil sampling kit, which is used to take an undisturbed sample of the soil. The soil is pushed up into a tube that can then be separated lengthwise into two halves for inspection and removal of the sample. It can also be used to perform the Standard Penetration Test (SPT) as prescribed by ASTM D 1586.

SPT Sampler Commonly used with the Cathead Kit, the split spoon sampler provides up to a 24″ soil core sample.

Made of durable plastic, sampler liners allow you to maximize sample recovery inside split spoons. To help preserve the entire recovered sample, plugs can be purchased to block the ends of the liners. Sampler liners are available in diameters from 1-1/2” to 2-1/2” and in 18” and 24” lengths.
