Easychem TOX

State-of-the-art Direct Read Discrete Analyzer for automated determination of acute toxicity in water samples based on bioluminescent bacteria, up to 45 tests per hour throughput.

4 universal, separate racks for continuous loading
of samples, calibrators and controls
  • Up to 40 reagents and controls can be loaded into the refrigerated compartment and distributed on 4 removable racks with 8 positions each (50 ml containers), with 8 extra position for 25 ml containers 10/20 ml containers can be adapted
  • 4 universal, separate racks for continuous loading of samples; each rack contains up to 15 samples (2 ml or 4 ml cups and/or 10-15 ml tubes), 8 extra positions for diluents; tubes size: 10-15 mm diam. and 40-100 mm height;
  • Long-life reusable cuvettes with integrated Cuvette Quality Assurance System; five steps washing station;
  • Bialkali photocatode luminescence detector;
  • Pre or post run sample autodilution;
  • Samples throughput: up to 45 tests / hour after 30 minutes incubation time;
  • Options: bar code reader for sample, bar code reader for reagent. 

Advantage and benefits
