Are you looking for an easy and non-destructive way for sampling pore water? The Rhizon samplers developed by Rhizosphere Research Products use a special membrane and the force of a vacuum to extract pore water. Our products are used in various fields of research and environmental issues all over the world.


Rhizon Samplers

Rhizon samplers offer a unique way to sample pore water from soils and sediments by creating a vacuum. Compared to other measures of extracting pore water, Rhizon samplers offer numerous advantages:

  • non-destructive; the soil structure stays intact
  • inert; there is no ion exchange and no adsorbtion
  • small diameter, so a low dead volume
  • hydrophilic membrane
  • once wet, only permeable for liquid (no air)
  • suitable for both saturated and unsaturated soils
  • suitable for meausring all dissolved components
  • disposable, but once installed suitable for repeated sampling
  • no need for additional filtering, this is already done by the membrane
