IBEX SCIENCES supplies high-sensitivity Universal pH Paper Indicator Strips (1–14 Range) from its primary scientific depot in Lahore, Pakistan. [1]
A pH indicator strip is a small piece of chemical-treated paper used to quickly check if a liquid is an acid, a base, or neutral. It changes color instantly when dipped, serving as a simple way to test everything from laboratory solutions to soil and water quality. [1]
Key Product Features
The standard universal testing kits sourced through the IBEX SCIENCES Supply Network include:
- Full Spectrum Scale: Measures the full range from pH 1 to 14. [1]
- Built-In Color Chart: Each pack includes a calibrated color guide to help you match your strip’s new color to its exact pH number within 15 seconds. [1, 2]
- High Sensitivity: Specially made to give distinct, clear color shifts so you do not have to guess the results. [1, 2]
- Multi-Pads or Premium Options: Alongside basic paper booklets, the IBEX SCIENCES Digital Catalog stocks premium Merck MQuant Non-Bleeding Strips (pH 0–14). The dyes on these premium plastic strips are chemically bound to the pads, meaning they won’t bleed or ruin your liquid sample. [1]
Reading the Color Scale
When the strip changes color, it tells you how strong or weak a chemical is: [1]
- pH 1 – 3 (Red/Orange): Indicates a very strong acid (like lemon juice or battery acid).
- pH 4 – 6 (Yellow): Indicates a weak acid (like milk or clean rainwater).
- pH 7 (Green): Indicates a perfectly neutral substance (like pure distilled water).
- pH 8 – 11 (Blue): Indicates an alkaline or basic substance (like baking soda or hand soap).
- pH 12 – 14 (Purple/Dark Violet): Indicates a very strong alkali (like liquid bleach or drain cleaner). [1, 2, 3]
Common Uses in Pakistan
- School & University Labs: Used heavily in Matric, F.Sc, and university chemistry experiments.
- Agriculture & Gardening: Testing soil pH to find out if ground conditions are right for growing crop varieties.
- Water Quality Monitoring: Checking swimming pools, drinking water, fish aquariums, and wastewater treatment loops. [1, 2]
