Hellma Analytics TRAYCELL 2.0 Schnellstartanleitung Seite 13

 Please note that the empty TrayCell has an absorbance of around 1.
To correct this characteristic absorbance, first carry out a reference
measurement with the solvent in which the sample was dissolved.
 You can then start taking measurements with the sample.
 Please note that the cap must be correctly positioned on the TrayCell
before you start measuring!
 If necessary, the sample can be recovered by pipetting once the
measurements are complete.
 Finally, clean the window and the mirror inside the cap.
