pH Level 1-14 for Acid Base Science Experiments
Wide range pH level test papers can measure pH 1-14 and are ideal for science fair experiments.
The indicator pads are mounted on high contrast white plastic strips and are convenient for dipping into test tubes
whether you are testing lemon juice, vinegar or baking soda.
This triple pad version is especially useful,
since it uses 3 different reference points, which can help avoid ambiguous results. If you want to economize & buy just one
type of pH paper, for use in acid base pH problems of a broad range of different substances, this is it.
Note: The number of strips per pack or vial is approximate.
- Wide range paper pH 1-14 for general use
- Three pad reference; 1 changes, 2 don't
- Resolution is 1 pH unit
Test Specifications; How to Use
- Dip strip in solution for 1-2 seconds; compare to color chart
- Solutions must be aqueous (water based)
- For soaps, wet the strip first; oils cannot be tested
- Deeply colored solutions can cause inaccurate readings
- 2+ year shelf life if kept sealed & out of direct sunlight
