pH-Fix 4.5-10.0 Indicator Sticks 6x85mm (10x100 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 that has been optimized to prevent solution contamination and allow for the measurement of highly alkaline or weak buffer solutions. When testing pH, the strips produce a permanent color change, even when left in place, such as when testing low ionic strength solutions. An immediate result is obtained by comparing the color of the four test zones with the included 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 increments. The pH indicator strips are suitable for many applications, both in the laboratory and in the field. They have the advantage over other pH measurement methods in that they require no 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 without sunlight.
