VITLAB® genius² dispensers are practically universally applicable and can be used with many organic and inorganic solutions. The materials that come into contact with media (borosilicate glass, Al2O3ceramics, FEP, ETFE, PFA, PTFE, platinum iridium and PP) are resistant to most acids, solvents and bases. The practical screwing mechanism and inner toothed bar enable a fast and precise volume adjustment. The simple-to-use calibration function helps meet all the requirements for test equipment monitoring with minimal downtime. Reagent loss while bleeding is avoided with the innovative recirculation valve.
