Plastic suction cups
Scope of application
Extracts soil solution to analyze inorganic solutes e.g., cadmium, lead, arsenic, antimony and phosphate); suitable also for all major nutrients (alkali metal and alkaline earth metals, nitrates, sulphates etc.- 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 acts as a protective sleeve for optimal hydraulic connectivity to the water-filled soil pores
