Cardinal Health pH Indicator Strip, Long Range 0 to 14, 4 Test Fields

Cardinal Health long-range pH indicator strips measure the full 0 to 14 pH scale with a 1.0 sensitivity and four test fields. The indicator dyes are bound to the cellulose fibers, so the colors will not run into one another, even in strongly basic solutions. The strips can be left in the solution until the final color change is completed, which makes them usable in unbuffered or very weakly buffered solutions. Each 6 x 85 mm (0.24 in x 3.3 in) plastic strip holds four 6 x 5 mm (0.24 in x 0.2 in) indicator papers and is long enough to keep your fingers out of the test sample. Sold as a pack of 100 strips.
