Mark tubes with perforated bottom

Laser-perforated mark tubes allow the sedimentation of a sample within the tube. This is achieved by filling glass wool into the perforated section. Thereby, a flow can be generated inside the glass tube, which creates a concentration of particles in the measuring range. This highly simplifies the examination of the sample.
