Answer:
The cuvette will only fit into the spectrophotometer in one orientation.
Explanation:
There is an arrow always marked on the cuvette that indicates how to place it inside the spectrophotometer. The sides of the cuvette also have small edges that if light passes through them, spurious light can be detected due to poor positioning. The spurious light does not get through the entire sample, if we want to measure the absorbance. With a cuvette in the indicated position, the procedure is measured and its reference value is taken, and then compared with other cuvettes to be used.
