Litmus pH Test Strips, Universal Application (pH 4.5-8), 100 Strips
This product contains 2, 5, 10, or 20 packs of 100 pH strips. Each strip is made of premium grade litmus paper intended for universal application. To test the pH of a solution simply dip the pH strip into your solution and the strip will change color. Quickly match this color against the color chart provided to obtain your solution's pH. Please see our infographic for common uses and examples of pH. To further the reliability of our products we randomly test each shipment we receive across multiple pH's to ensure product quality. The pH color chart intervals are: 4.5 (acidic), 4.8, 5.1, 5.4, 5.7, 6, 6.3, 6.6, 6.8, 7 (neutral), 7.3, 7.5, 7.8, 8 (alkaline).
1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.
2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry!
3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral.
Store in a cool, dry place away from sunlight.
