AMS Dual-Purpose Soil Recovery Probes can be used with or without liners.
AMS dual-purpose soil recovery probes include the slotted soil probe body, top cap, 10" cross handle, a plastic liner, and 2 plastic end caps. The probe body has a window slot that allows for direct observation of the soil samples after the soil samples have been collect either directly into the soil probe body or into a plastic liner. These probes also feature the AMS "Reach and Grab" system that consists of a specially threaded top cap which allows the plastic liner to protrude from the top of the probe cylinder. This system makes it easy to remove the liner from the soil probe body without disturbing the sample.
The liners used with AMS Dual Purpose Soil Recovery Probes are 1/8" diameter smaller than the soil probe diameter and 1 3/4" longer than the specified length of the sampler.
