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, sediment samples inside the core sampler are 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 can accommodate up to a maximum of 500mm. 【Features】 ■ Can extrude sediment samples collected with a core sampler ■ The length of the extrudable sample can accommodate up to a maximum of 500mm ■ By changing the size of the extrusion rod head, it can also be used with samplers other than our products *For more details, please refer to the PDF document or feel free to contact us.
