Plastic suction plates
Scope of application
Areal extraction of soil solution for the quantitative analysis of solute fluxes; application in field studies and lysimeters (Excursus: Suction cups product finder)
Features
Suitable for inorganic solutes with high sorption coefficients
Heavy metals (Cd, Pb, Zn), metalloids (As, Sb) and phosphates
High hydraulic conductivity
High Bubble Point
Open-grained polyethylene-structure or polyamide mesh acts as a protective sleeve to obtain a optimal hydraulic connectivity to the water-filled soil pores
Tongue and groove system allows construction to any size
For lysimeter application rounded elements available
