pH Indicator Strips

$20.95$22.95

Our pH strips provide accurate colorimetric pH indication. The dye is covalently bound to the paper carrier on a plastic strip. No bleeding, even in strongly alkaline solutions. Strips can be immersed in the sample for extended periods, so weakly buffered solutions can be tested with accuracy. These are excellent for testing casing layers, substrates, and compost.
