Troubleshooting
Here are some tips for best data-collection practices:
Allow the Colorimeter to warm up for about 5 minutes before calibrating.
Fill a cuvette two-thirds to three-fourths full with liquid, including the
calibration blank, so that the light travels through the liquid reliably.
After filling a cuvette with liquid, seal the cuvette with a cap to prevent spills.
Make sure to place a cuvette in the Colorimeter so the path of the light source
travels through the clear sides of the cuvette. An arrow to the right of the
cuvette slot shows the light path.
For best results, use one cuvette to make all your measurements for a given
experiment.
If you calibrate a Colorimeter and then change the wavelength, calibrate the
Colorimeter again to ensure the proper identification of the new wavelength.
For best results, a sample's absorbance or transmittance values should fall within
these ranges:
percent transmittance:10–90%
absorbance: 0.05–1.0
We have found that Beer’s law experiment results begin to lose their linearity at
absorbance values above 1.0 (percent transmittance values less than 10%). If you
have a solution that transmits such a low level of light, consider diluting the
solution so that it falls within this range.
