Colorphast pH Indicators
Description
Description
These pH strips provide accurate colorimetric pH indication. To prevent bleeding, even in strongly alkaline solutions, the dye is covalently bound to the paper carrier on a plastic strip. Strips can be immersed in sample for extended periods, so weakly buffered solutions can be tested with accuracy. The universal strip tests the full 0-14 pH range with a sensitivity of 1 pH units. Intermediate range indicators provide a sensitivity of 0.3-0.5 pH units and narrow range strips provide a sensitivity of 0.2-0.3 pH units. Use distilled water for testing.
Also referred to as ph strips.
