Product description

Our specially developed TerraElute percolation system is a fully automated laboratory device for the elution of inorganic and organic substances from solids—in accordance with DIN 19528 / suitability testing under the Substitute Construction Materials Ordinance (EBV) or the Landfill Ordinance. We further developed our TerraElute in 2026, and it is now also available in various sizes and configurations, enabling it to accommodate different sample volumes and applications. A single master unit controls up to five racks with up to twenty columns each simultaneously (up to 10 racks / 40 columns available upon request). The equipment per rack can be configured for either short-column tests and/or comprehensive column tests.

Features

Automatic and efficient execution of the percolation process in upward flow according to DIN 19528
Water sensors for detecting saturation in each column
Automatic calculation of actual porosity and switching to percolation mode
Flow control via piston-type pumps, deviation <1% from setpoint
Automatic flushing mode
Quick-connect fittings on all hose connections and a barcode scanner for checking columns and vials in and out simplify workflows and enable convenient operation
Export of data for the test report
Color touch display: recognition of free positions for sample columns and bottles or finished columns and fractions

Components

Master	Dimensions: 1,652 x 300 x 624 mm (HxWxD) Aluminum frame with heavy-duty feet (can be secured to the floor or wall) PLC control system with color touchscreen, including programming for data entry, processing, transmission, visualization, and alarms Barcode reader for automated data entry via QR and/or barcodes from your LIMS (alternatively, import of a CSV file) 5-liter V2A reservoir with automated deionized water replenishment via solenoid valve (dosing unit for e.g., CaCl₂ available upon request), including strainer and pressure reducer (0.3 bar), and level sensors for minimum/maximum water levels A maximum of 5 racks can be connected to a TerraElute Master.
Rack	Dimensions without columns: 1,652 x 500 x 624 mm (HxWxD); with columns, the height is up to 1,900 mm For up to four sample columns and four eluate vials, allowing for four simultaneous short column tests or a comprehensive column test (ASV) with four fractions. Flexibly adjustable column holder for 1–4 glass columns Bottle rack for 4 bottles, each 1–10 L, in a carrying basket for easy removal. Includes lid holders with a rinse line and 4 GL-45 lids (vented) for eluate bottles Rinse water line behind each column, rinse water collection tank with float switch and micro-submersible pump for discharge into a wastewater connection
Columns	Glass columns (1–3 kg, max. 10 cm Ø) with GLS-80 closure Completely airtight lid Quick-connect couplings

Optional components

TerraElute Mix

Expansion module for the TerraElute Master, for the automatic dosing of elution agent additives (e.g., CaCl₂, additives, cleaning solutions, etc.)
