UGT Suction probe S14 MINI with ceramic tip, without standpipe

The suction probe S14 MINI has no standpipe; it consists only of a small ceramic tip (Ø10 x 25 mm) that is firmly glued to an acrylic adapter. This small design is particularly suitable for collecting percolate in small lysimeters. The ceramic tip is connected to a 200 cm long suction hose via the acrylic adapter. Both the hose itself and the hose connection are made of inert PE to prevent contamination of the samples. The suction hose with Luer-Lock adapter can be connected to a water stop valve or a UGT connection cap GL4 for sample bottles.

How it works

When a vacuum is applied, the soil water is sucked out of the soil through the suction cup and collected in the connected sampling bottle. The suction probe is suitable for both permanent constant vacuum in combination with a suction probe system and for a single application of a vacuum.

Optionally, you can carry out sampling manually with collection syringes. Use our practical set of 10 collection syringes with locking holders and Luer lock connection.

Use of a groove auger during installation

For optimal installation of the suction probe in the soil, we recommend using a suitable groove auger. This tool is used to pre-drill a hole with a diameter that is slightly smaller than that of the suction probe. A diameter that is too large can favor preferential flow paths along the suction probe, causing additional water to be directed to the suction cup. This could falsify the measurement results. The appropriate pre-drill not only makes installation easier, but also ensures a proper connection between the suction probe and the surrounding soil, which ensures precise sampling.
