ColorpHast® pH Strips. EMD Millipore
Manufacturer: EMD Millipore Corporation
All of the ColorpHast® products include bright, easy-to-read color comparator charts. The strips are simply extracted from the package, dipped into the test solutions, and read without any equipment required. The indicator changes the color of the strip based on the pH of the sample, and the color change is clear and easy to distinguish against the distinct results shown on the comparator chart. Nothing could be easier, especially for those times when samples need to be measured outside of a standard laboratory setting. Within seconds of dipping a ColorpHast strip into your sample, you have the results you need. There is no waiting for pH meters to equilibrate, no need to calibrate the meter again and again. You can be assured that these strips will never affect the sample you are measuring. The indicators used to express the pH of the samples are covalently bonded to the strip itself. Since these indicators are irreversibly bound, they will never bleed, form uneven color zones, or fade under intense light. This is an important and unique feature of ColorpHast strips compared to most other pH methodologies.
