pH-Fix 6.0-10.0 Indicator Sticks 6x85mm (10x100 pcs)
These pH indicator strips are ideal for pH determination in the range of pH 6 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 contamination of the solution and to allow measurement of highly alkaline or weak buffer solutions. When testing pH, the strips cause a permanent color change, even when left in place, for example, when testing low ionic strength solutions. An immediate 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 the position of the pads on the strips. The results are easy to interpret and can be reliably determined, as the pH gradations are in steps of 0.3. 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 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 come in packs of 100 disposable strips. They can be stored unopened for 2 years without sunlight.
