When taking measurements, the outside of the cuvette
must be dry and free of syrup, ngerprints, oil, or dirt.
Wipe it thoroughly with a lint-free cloth prior to insertion.
Make sure cuvettes and syringes are completely
dry before using. Excess water will leave streaks
in the syrup sample which may aect results.
Dispense or pour the sample slowly. When transferring
the syrup into the cuvette, be careful not to generate
bubbles as they may cause inaccurate readings.
