Our specially developed TerraElute 20 percolation system is a fully automatic laboratory device for the elution of solids according to DIN 19528. The laboratory device consists of an aluminum frame with two levels. In each level there are 10 sample racks or 20 sample columns.

This allows you to process 20 different samples with a dry weight of up to 3 kg simultaneously. In each case, 4 eluate fractions are obtained. With restrictions, 40 samples can be analyzed, with 4 fractions obtained in one half and one fraction in the other half. The 40 sample columns can be controlled individually.

Features

• Automatic and efficient execution of the percolation process in upward flow according to DIN 19528
• 40 sample columns in 20 sample racks can be operated simultaneously and controlled individually
• 20 detailed, 40 simple column tests or a combination of both are possible at the same time
• For extensive column tests, 4 volume-dependent eluate fractions are automatically and sequentially collected in amber glass bottles (fraction bottles) with variable filling volume
• Sample columns and bottles can be exchanged and reloaded independently of each other during operation
• Both sample columns per sample rack can be processed in parallel
• Barcode scanner as network-independent interface for data transfer to the TerraElute 20
• Import of sample parameters for flow rate calculation via QR code
• Barcode scanner for efficient recording and allocation of fractions to sample columns using QR and barcodes
• Export of data for the test report
• Color touch display: recognition of free positions for sample columns and bottles or finished columns and fractions
