Description Of The Instrument; Display And Operation Keys - MERCK RQflex plus 10 Mode D'emploi

1 Description of the instrument

Your RQflex® plus 10 is a versatile, precise instrument. It is part of the
Reflectoquant® system with the components:
• instrument RQflex® plus 10
• Reflectoquant® tests
• test- and batch-specific bar-code strip
According to the principle of reflectometry (remission photometry), diffuse reflected
light from the test strip or after transmission through a cell is measured. Just as in
classical photometry, the difference in intensity of emitted and reflected light
allows a quantitative determination of the concentration of specific analytes.
