The "KZP-S" is a device used to extrude sediment samples collected with a core sampler. By pushing the tip of the extrusion rod (extrusion rod head) into the core sampler, the sediment sample inside the core sampler is extruded. When extruding the sample, the position of the pin inserted into the hole of the extrusion rod can be changed to adjust the length of the extruded sample. The length of the sample that can be extruded is compatible with a maximum length of 500mm. 【Features】 ■ Can extrude sediment samples collected with a core sampler ■ The length of the extrudable sample can be adjusted up to a maximum of 500mm ■ By changing the size of the extrusion rod head, it can also be used with samplers from other manufacturers *For more details, please refer to the PDF document or feel free to contact us.
