AMS Soil Core Samplers allow you to collect relatively undisturbed soil core samples from the subsurface or from pre-augured boreholes. AMS soil core samplers collect relatively undisturbed soil core samples into liners that may be easily transferred to a lab for soil profiling or chemical analysis. The liner may also be extruded in the field for examination of the soil core sample. Soil core samples are available in carbon steel or stainless steel, and are sized by the outside diameter of the liner. AMS Signature Series core samplers feature a heavier thread than the standard 5/8" NC thread AMS augers. The signature series thread is more robust and will connect with only 2-1/2 turns. Complete Soil Core Samplers Includes: Core cup and cap, 2 plastic end caps, and plastic liner. Please make sure any AMS samplers you intend to use together share a common connection type.
