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.

The Sediment Corer is easy to handle and can be operated manually in shallow waters with a push rod or on a rope simply using gravity in greater water depths. During descent the plastic valve flap on top of the transparent plexiglass tube is held open to let the water flow freely through the tube. To retrieve the sample the corer is lifted from the sediment and the water pressure at the valve flap closes the tube. A vacuum is holding the sediment sample in place and is preventing washout. Out of the water the provided piston is put into the lower end of the tube. The tube holder with rope stirrup is taken off and the tube with the core sample is placed onto the piston. When the tube is now pressed onto the piston the core sample will be removed for examination.

The Bottom Sampler acc. to Van Veen is a qualitative sampler to achieve low-disturbed sediment samples in soft or medium hard grounds from any desired depth. It consists of two clamshell jaws connected by a hinge. During descent both levers are locked wide apart and the jaws are open. Upon touching the water bed the locking mechanism is released and when the rope is pulled taut to raise the sampler the jaws close. During retrieval the jaws are holding the sample and prevent sample wash-out. Additional flaps on top of the heavy version 437 333 allow to inspect the sample before retrieving.
