Used throughout the Geotechnical Sampling Industry, this set of 6 - 1" long liners stack on top of each other to take the place of a traditional 6" long liner. These precisely cut 1" rings are designed to fit inside many of the geomatic lab testing equipment. The 2.5" Outer diameter of the liner allows it to fit seamlessly inside the AMS Soil Sampler or the Cal Mod Geotechnical Split Barrel Sampler with a 2.5" ID.The plastic Geotechnical Sample Canister is designed to store all 6 - 1" rings for secure transportation. The canister has a lid on both the top and bottom, allowing you to easily access all the samples without damaging them.
