pH 1-11 Indicator Paper, refill, 3 x 5 m, rolls 30 x 5 m

This pH Indicator Paper Refill Pack is designed for use with the pH Indicator Paper Dispenser Roll for pH Determination in the pH 1 to pH 11 range (product code: PH0203). Each of the 3 rolls in this pack measures 5m (length) x 6mm (width) and is manufactured from high-quality filter paper to ensure optimum quality. The paper rolls are supplied unperforated so to test your sample you simply need to tear off the required length. At each pH value, the paper changes to a single colour which can be matched to the colour chart which is included with the refill pack or supplied with the dispenser. The pH gradations on the colour chart are in increments of 1. The pigments used on the colour chart have been precisely formulated to perfectly match the reaction colour of the pH indicator paper. This allows for results to be reliably determined and easily interpreted. The pH indicator paper is suitable for many applications, both in the laboratory 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 Refill Pack is supplied as a pack of 3 refill rolls. The rolls can be stored unopened for 2 years without sunlight.
