SPE20 SUCTION CUP

Measurements:

Applications:

The SPE20 contains a specialized membrane specifically designed for tough applications such as sampling heavy metals and where porous ceramics are inappropriate.

 

Applications

For detection of herbicide, pesticide, and heavy metals

 

Benefits

Only materials with sample contact are nylon and polyethylene 
Low sorption

 

Limits

Buble point is 100 kPa, but the porous PE cover allows water to flow only up to 20 kPa

SHAFT Ø 2 cm; Acrylic
POROUS CERAMIC Ø 2 cm; length 6 cm
BUBBLE POINT -100 kPa (only allows water flow up to -20 kPa)

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.

Benefits

  • Simplifies installation of shafts
  • Avoids slurrying
  • Multipart - divisible - extendable
