pH 5–9 Indicator Paper in a Roll 5 m 10 x 5 m

This pH Indicator Paper Dispenser Roll is ideal for pH determination in the range of pH 5 to pH 9. The pH Indicator Paper Roll measures 5 m (length) x 6 mm (width) and comes in a refillable plastic dispenser that ensures the long-term stability of the pH paper by protecting it from many external contaminants. The pH Indicator Paper Roll is made from high-quality filter paper to ensure optimal quality. The paper roll comes unperforated, so you simply need to tear off the desired length to test your sample. At each pH value, the paper changes to a single color that can be matched to the color chart included in the dispenser. The pH gradations on the color chart are in 0.5 increments. The pigments used on the color chart have been precisely formulated to perfectly match the reaction color of the pH indicator paper. This allows for reliable results and easy interpretation. The pH indicator paper is suitable for many applications, both in the lab and in the field. The advantage over other pH testing methods is that no additional equipment is required compared to liquid test kits and digital meters. This makes it more portable, durable, and easily replaceable. The pH Indicator Paper Dispenser Roll is supplied as a 1-pack, and refill rolls are also available. The rolls can be stored unopened for 2 years without sunlight.
