Areal extraction of soil solution for semi-quantitative analysis of solute fluxes; application in field studies and lysimeters see ( Suction cups product finder)

  • Glass grains sintered without use of additives or bonding materials
  • Small specific surface area
  • Low sorption capacity for organic solutes
  • High bubble point
  • Exclusive use of borosilicate glass and PTFE
  • Detection of preferential flow better than with suction cups
  • Developed by Prof. Dr. Jan Siemens
