The set is very suitable for sampling less cohesive soil layers below the (ground) water table to a depth up to 5 metres. The piston sampler is also suitable for sampling sediments with a sand content. The samples show little disturbance and therefore are suitable for very accurate profile description. With the set 0109SA a piston sampler is used with a sample gutter to empty the sampler in. The sampler with various accessories can be transported in the field in a carrying bag.
