一般描述

6 replacement rolls (of 4.8 m), for 109564, 109565 Neutralit^?
MQuant^?pH indicator papers supplied in rolls are perfectly suited for longterm storage, since they are protected against external influences, such as moisture, light, and ambient gases. These pH indicator papers are manufactured by impregnating high-quality filter paper with indicator or mixed-indicator solutions. The paper is always ready to use; it is easily pulled out of the plastic reel and can be torn off in the necessary length. The pH value is measured semi-quantitatively by visual comparison of the color formed on the paper with the fields of the color scale. This article contains replacement rolls without color scale for article 109565.
