Box-shaped sediment sampler with dividing sheets
The Bottom Sampler acc. to Lenz is a modified version of the Ekman-Birge model. This precise quantitative sampler is equipped with dividing sheets to separate the sample into 5 layers of 20 mm thickness. These layers can then be removed separately for individual examination. The Lenz sampler consists of a sturdy-walled metal cabinet equipped with two spring-loaded jaws which are released by a messenger. Two light plates cover the top opening of the sampler to prevent the sample from being washed out during ascent.
