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.

Advantages
- Equipment and sets for the semi-automatic performance of column tests
- Available as individual elution columns, semi-automatic elution units or professional, fully automated percolation units, which enable a high sample throughput
- Simple, tool-free assembly and filling of columns
- Stable and accurate flow even with back pressure through the filled column
- Strong glass columns made of borosilicate glass 3.3
- Fastener clamp to prevent leaks
- Secure against the dry running of the pump and water jets
- Intuitive operation and easy calibration
- Available in dimensions to meet the requirements of a country’s regulations
- Modular design for integration from a simple column range to an upgraded higher-quality system
- Special editions/ accessories available
Leachate Collection Columns Equipment Options:
Applications
- To perform manual column tests (Standard Set) in conjunction with existing laboratory equipment such as pumps, water tanks, bottles etc. through to semi-automatic Stainless steel column minimises the disturbance of samples. Optional: Junctions for e.g. Redox-electrodes and mini suction cups
- Column base with integrated suction plate for unsaturated experiments
- Tube made of acrylic glass. Possibility to connect junctions for mini suction cups
- Drop weight for column packing
