There are two sets of liner samplers available.
This is the liner sampler set for soft soils, due to its bayonet connection.
The sample, while still in the liner, can be stored in a container which can be sealed for transport to the laboratory.
In case of an undisturbed sample, it is often difficult to remove the sample from the sampler tube. This type of corer uses a sample liner inside the sample tube; this facilitates easy removal of the sample from the tube. The samples can also be viewed directly in the field, without having to touch them.
