pH-Fix 4.5-10.0 Indicator Sticks 6x85mm (100 pcs)

These pH indicator strips are ideal for pH determinations in the range of pH 4.5 to pH 10. The rigid plastic strips measure 85 mm (length) x 6 mm (width) and feature four separate pH test zones to cover the intended pH range. Each test zone has been infused with a non-bleeding pH indicator compound, optimized to prevent solution contamination and allow for the measurement of highly alkaline or weak buffer solutions. When testing pH, the strips provide a permanent color change, even if left in place, e.g., when testing low ionic strength solutions. An instant result is obtained by comparing the color of the four test zones with the enclosed pH color chart. The pH color chart accurately matches both the color and position of the pads on the strips. The results are easy to interpret and can be reliably determined, as the pH gradations are in 0.5 unit increments. The pH indicator strips are suitable for many applications, both in the lab and in the field. They have an advantage over other methods of pH measurement in that they do not require additional equipment compared to liquid test kits and digital meters. This makes them more portable, durable, and easily replaceable. The pH indicator strips are CE-IVD marked and come in packs of 100 disposable strips. They can be stored unopened for 2 years out of direct sunlight.
