Macherey-Nagel Indicator paper- 7.0 - 10.0 Pack of 3 90315

Roll length 5 m, 10 mm width. With two colour zones. Plastic box with 1 roll of indicator paper and colour scale. Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colors, simplifying and precisely assigning the pH value.
