Note To minimize instrument error with highly concentrated samples, make dilutions to
ensure that measurements are made within these absorbance limits:
• For micro-volume measurements, maximum absorbance at 260 nm (for nucleic acids)
or 280 nm (for proteins) should be less than 62.5 A.
• For measurements with 10 mm pathlength cuvettes, maximum absorbance at 260 nm
(or 280 nm for proteins) should be less than 1.5 A, which is approximately 75 ng/μL
