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