UV VIS PHotometer
Remove the desiccant from the sample chamber before starting the machine. It is forbidden to open the sample chamber cover during the self-test.
The solution in the cuvette should be 2/3~4/5 of the height of the dish, and should not be overfilled to prevent the liquid from overflowing and corroding the instrument. The cuvette should be kept clean during the measurement, and the droplets on the wall of the pool should be wiped dry with a mirror paper. Do not pinch the translucent surface with your hands. When measuring the UV wavelength, a quartz cuvette is required.
