Photometers are within the top 10 most commonly used general laboratory equipment. Thus, photometric analysis are among the most frequently used applications in modern laboratories and are often found at the very beginning of a lab workflow. Subsequent tests are consequently prepared according to photometric determinations. If these determinations are based on incorrect data, the errors could accumulate exponentially throughout the workflow and, in worst case scenario, generate inaccurate results. That is precisely why dependable and accurate photometric measuring results are extremely important. And since photometric measurements can only be as good as the combination of instrument and accessory, the choice of cuvette is just as crucial as the selection of the correct instrument itself.
