Answer :
When handling a cuvette, it is important to avoid touching the inside walls with your fingers, as the oil and debris from your skin can interfere with the accuracy of the spectrophotometer readings.
To prevent this, hold the cuvette by the smooth sides that are on the outside, as they are less likely to affect the quality of the solution inside. Additionally, it is crucial to clean the cuvette before inserting it into the spectrophotometer to ensure accurate measurements. This involves washing the cuvette with distilled water, followed by wiping it dry with a clean lint-free cloth. By following these procedures, you can ensure accurate and reliable readings from your spectrophotometer.
