SKS20/SPES20/SIC20 SUCTION CUPS WITH SHAFT STORAGE
The SKS20/SPES20/SICS20 allows for water and solute collection down to depths of 8 meters that could not normally be collected from other pore water samplers. Available with all three sampling cup materials (Al203 Ceramic, Polyethylene Membrane, and Silicon Carbide).
Thanks to its unique design, the SKS20/SPES20/SICS20 collects the sampled solutions and stores them inside of the shaft, where they can later be collected by applying pressure to push the sampled solution up to a sampling bottle at the surface. At these depths, water cannot be collected by applying suction because of cavitation.
Cost effective; sampling bottles are not needed.
Extracted soil water is stored at soil temperature.
Chemical suitability limited to the chosen suction cup material.

Auger Kits for Pore Water Samplers and Tensiometer
The cutting edge of the auger has a tapered tip similar to the shape of a Tensiometer or pore water sampler. Thus, the bore hole is large enough to insert the shaft, but the cup will have a tight and perfect fit to the soil.
The not recommendable slurrying of the cup with quartz clay can be avoided.
A divisible auger set includes:
- Cutting edge with tapered tip
- Handle with hammering head
Parts have threaded connection and can be extended with one or more 100 cm extension rods.
- Simplifies installation of shafts
- Avoids slurrying
- Multipart - divisible - extendable
