Cuvette cleaning

The latest pharmacopoeic instructions require enhanced purity control of the cuvettes used for spectroscopic measurements. The Starna CellClean solution means great help for cleaning the cuvettes contaminated with hard-to-remove samples (e.g. biological samples, oils, waxes, etc.). CellClean is an acqueous based cleaner with a unique combination of purifying ingredients, which dissolves and decomposes the contaminants preparing the cuvettes for new measurements.
