Neutral Litmus Test Strips, 100-Vial

These Neutral Litmus Test Strips provide a quick qualitative assessment of whether a solution is acidic or alkaline. Each vial contains 100 papers that turn red in acidic solutions (pH below 7) or blue in alkaline solutions (pH above 7). No color comparator chart is needed, though the strips do not provide a specific pH value. Each strip measures approximately 48mm long and 6mm wide (1.875" x 0.25"). Accurate, reliable, and easy to use, these test papers are a standard tool for laboratories, schools, industrial testing, and home brewing.
