The multisampler has been developed originally for sampling of wet, solid as well as fluid material. The standard set is suitable for sampling up to a depth of 5 meter. The materials used for the multisampler are stainless steel, NBR- rubber (the piston) and transparent acrylic plastic (sampling tube). The standard set (with bayonet connection), among other items, contains: a multisampler, inclusive of two cutting heads (one for fluid- and one for solid material), sampling tubes, pistons, extension rods, a top-piece and various accessories. The complete set can be transported in a carrying bag with shoulder strap. Using the multisampler it is possible to take anaerobe samples in a wide variety of wet materials, solid as well as fluid. Using the piston rod (usually extended by means of a wire-line) it is possible to move the piston in the sampling tube while this tube is held stationary. In this way the original stratification of the sampled material is maintained.
