The SPE20 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).

Applications

Thanks to its unique design, the SPES20 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.

Benefits

• Cost effective; sampling bottles are not needed
• Extracted soil water is stored at soil temperature

OPTIONAL ACCESSORIES

Auger kits for pore water samplers and tensiometer

Designed to simplify shaft installation, 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 less-than-ideal process of slurrying of the cup with quartz clay can be avoided. A divisible auger set includes: a cutting edge with tapered tip and a handle with hammering head. Parts have a threaded connection and can be extended with one or more 100 cm extension rods.

Sampling bottles and storage box

Soil water sampling bottles made of Duran glass, available in three sizes. Bottles are implosion proof, have a plastic coating as chip guard and include a silicon rubber gasket with two connectors. There is also a clip for upright attachment on walls. In the sampling bottle box, up to 6 sampling bottles can be stored, the lid is covered with isolating material, latches shut the box securely, and the suction tubes are led through sealed fittings on the side of the box.
