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.

Simple, completely impregnated indicator papers without colour scale. For orienting measurements and adjustments in different pH ranges.

Clear, Colourless pH Buffer Solutions. Tested and ISO17025 Certified at 20 °C, supplied with a detailed Certificate of Analysis which outlines traceability to N.I.S.T. Temperature dependence data is printed on the label as are lot numbers and expiry dates. Containers made of HDPE.* Phthalate freeHazardous Substance DataSDSLink
