The MAGO 4 is a walk-away analyzer that allows processing of samples in ELISA, IFA, hemoagglutination (TPHA), seroagglutination (Widal-Wright) and Allergy (specific IgE capture procedure) simultaneously. It increases efficiency through the simultaneous processing of up to 12 ELISA assays (on four microplates) or 16 IFA tests (slides) in one run. It offers 104 sample positions, 192 pre-dilution positions and 27 positions for reagents, standards and controls.
