This translucent teflon and stainless steel sampler is specially suitable for sampling and accurately making visible the layers in deeper containers, basins, monitoring wells with a diameter exceeding 38 mm, etc. The sample can be transported without disturbance in the transport tube. The cable-operated liquid layer sampler can not be used in thick, viscous fluids. After sampling, the thickness of the sludge- and floating layers can be measured, as, in the translucent tube, these are visible in the origial position and thickness. The teflon tube can be cleaned easily and effectively.
