Rinse the cell shaft with distilled water.
Cells have to be clean, dry, and free of fingerprints and scratches.
Therefore, clean them regularly:
1
Clean the cells inside and out with hydrochloric acid or
laboratory soap.
2
Rinse out several times with distilled water.
3
Let them dry in the air.
4
Only hold the cells by the top or by the light protection cap so
that the optical path is not impaired.
5
Before measuring, clean the cell with the enclosed cleaning
cloth.
Scratches in the glass change the optical characteristics of the cell and
falsify the measured value. For this reason, never use scratched cells!
