Depending on the application, various tubes are available for groundwater sampling. The tubes vary in diameter, length, type of material and package. Polyethylene tubes are certified according to KIWA BRL K563. Silicon rubber tubes are tested within the ETU-hallmark. During this test the products are subjected to a strict, selective leaching procedure for establishing the degree of discharge of toxicological substances to water.

Polyethylene tube is most commonly used as a transport tube for groundwater samples. To avoid cross contamination to other wells the tube is used only once. The tube meets the physical-chemical requirements as laid down in the DIN 8072 standard and KIWA BRL K563.

Furthermore there are teflon (fully inert) tubes available as transport tubes in various diameters. A silicon rubber tube (in various diameters) is applied as pumping tube in combination with the peristaltic pump (manual or electrical). Here too, the tube is replaced before every sampling to avoid crosscontamination. The tube meets the requirements as set by the pharmaceutical- and food industry and the ETU-hallmark.

To prevent that during unrolling tube gets in a knot, it is recommended to apply a tube dispenser (art. 122000). The tube dispenser is suitable for tubes in various diameters. To avoid that tube endings are contaminated by touching the soil (or slide from the sampler flask) the so called ‘third hand’ can be applied. It can also be used to clamp 0.45 micron groundwater filters.
