Kommentar:  Dokumente engl.

The ETI-MAX 3000 is a fully automated microtiter plate analyzer performing the complete sample processing (sample pre-dilutions, sample and reagent dispensing, incubations, wash processes, plate transports) as well as the photometric measurement and evaluation. The Instrument is controlled via the Windows PC software ETI-MAX 3000. This software, which was specifi­cally designed for this purpose, allows the user to process the pre-defined assays of DiaSorin as well as assays programmed by the user. The clear structure with intuitive user-guidance allows simple and quick operation of daily routine jobs as well as programming of user-specific assays.
