How to use the spectrophotometer (Spec 20\/20D)<\/span><\/strong><\/span><\/p>\n

1. Turn on the instrument and let it warm up for at least 5-10 minutes.<\/span><\/p>\n

2. Select the wavelength with the dial next to the sample compartment.<\/span><\/p>\n

3. With the sample compartment closed and empty, adjust the % Transmittance (zero percent transmission of light) to read 0% T using the left front dial.<\/span><\/p>\n

4. Place a clean (no fingerprints), dry cuvette filled approximately 3\/4 full of the blank sample (solvent only) in the sample compartment. Close the sample compartment. Adjust the % Transmittance to read 100% T (100 percent transmission of light) using the right front dial.<\/span><\/p>\n

5. Remove the blank cuvette and place the cuvette containing the sample in the sample compartment. Close the sample compartment. Read and record the value registered on the meter.<\/span><\/p>\n

Note: Every time the wavelength of light is changed, the instrument must be recalibrated to read 0% T and 100% T with the blank. Repeat steps 2-5.<\/span><\/p>\n
