ENSURE ACCURATE MEASUREMENTS
• Each time the cuvet is used, tighten the cap
to the same degree.
• Discard the sample soon after the reading is
taken to avoid permanently clouding the glass.
• All glassware used to contain the standards
and the samples should be maintained clean,
washed with the HI93703-50 cleaning solution
and rinsed with HI 93703-0 or turbidity-free
water.
• Collect the samples in clean glass or plastic
bottles, fit stoppers and perform the analysis
quickly. If necessary, store the sample in a
cool, dark place, for up to a maximum of 24
