pH-Fix 0-14 Indicator Sticks 6x85mm (10x100 pcs.)

These pH indicator sticks are ideal for pH determination in the range pH 0 to pH 14. The rigid plastic sticks 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 for the measurement of highly alkaline or weak buffer solutions. When testing pH, the strips produce a permanent color change, even if left in place, e.g., when testing solutions with low ionic strength. An immediate result is obtained by comparing the color of the four test zones with the enclosed pH color chart. The pH color chart precisely matches both the color and the position of the pads on the strips. Results are easy to interpret and can be reliably determined, as pH graduations are in increments of 1. The pH indicator sticks are suitable for many applications, both in the laboratory and in the field. They have an 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 sticks are supplied in packs of 100 disposable sticks. They can be stored unopened for 2 years out of direct sunlight.
