Suction probes with ceramic cup

• With this suction probe the percolateis drawn from the soil to a ceramic cup (P80; 20 x 50 mm). The acrylic glass standpipe (Ø 20 mm) simultaneously serves as a collection compartment. No additional sampling vessels are therefore necessary but may be connected as required. The storage of the sample in the standpipe means that it is extensively kept at soil temperature. Transport and vacuum line are kept separately and can be individually sealed by drain taps at the hose connections. The structure of this suction probe permits a completely autonomous operation and prevents the percolate being drawn back intothe soil in dry phases. Both the tubes themselves and the tube connections are made of inert PE to prevent falsification of the samples. The suction probes with ceramic cup are also offered as an underground version. Instead of the standpipe, this design has a tube to the soil surface which is connected to a separate sampling vessel. For the taking of larger samples the ceramic cup with integrated 100 ml collection vessel is recommended. This suction probe can also be equipped with a glass cup instead of a ceramic cup for the detection of organic substances such as pesticides or DOC without absorption losses.
