Leachate Collection Columns

Leachate Collection Columns from ecoTech, Germany are designed for the precise monitoring of leachate in soils in order to comply with strict Government guidelines. The equipment performs saturated and unsaturated percolation tests of mineral residues. This determines breakthrough curves. Leachate Collection Colums simplifies and reproducibly ensures the performance of column elutions.
