These Soil Core Liners function as sample retaining cylinders when used in the Soil Core Sampler for obtaining a representative and mostly undisturbed sample of soil.
The liners are thin walled cylinders of the selected clear or metallic material that fit snugly into a soil coring cylinder. As the coring cylinder is advanced the soil core is pushed into the liner in a mostly intact and representative condition. The liner can then be removed to examine the soil core without the sample falling apart.
