Universal Ph Indicator
Product Code : SCL-CL-11605
Universal Ph Indicator (SKU SCL-CL-11605) is universal indicator test paper covering the full pH 0–14 scale. A strip dipped in a solution changes colour, showing whether the liquid is acidic, neutral or alkaline and roughly how strongly. It is a routine consumable for school science, college chemistry and water-testing practicals. Science Lab Supplies, a laboratory chemicals supplier in India, sends it from Ambala to schools, colleges, institutes, tender contractors and distributors.
Specifications
This universal pH indicator is a paper test strip impregnated with a mixed indicator, so one strip gives a colour across the whole range from pH 0 to pH 14. It needs no power or calibration, which makes it practical for large classes and field samples.

Applications and Experiments for the Universal pH Indicator
Universal indicator paper is used wherever students need an approximate pH value rather than a simple acid or base answer. It fits the acids, bases and salts chapters of NCERT science, Class 11 equilibrium, and quick checks of water, soil extracts and household solutions in project work.
- NCERT Class 10 science: estimating the pH of common solutions such as juices, soap solution and dilute acids.
- NCERT Class 7 science: sorting acids, bases and neutral substances.
- Class 11 chemistry: linking the pH scale to ionic equilibrium.
- Environmental science projects: checking the pH of water samples and soil extracts.
Read the strip soon after dipping and compare its colour with a pH colour chart; keep the paper dry and away from acid or ammonia fumes.

Frequently Asked Questions
What pH range does this universal indicator paper cover?
It covers the full scale from pH 0 to pH 14, so a single strip can tell a strong acid from a weak acid, a neutral liquid or an alkali by its colour.
How is universal indicator different from litmus paper?
Litmus only shows whether a solution is acidic or basic. Universal indicator paper changes through a series of colours, so students can estimate an approximate pH value as well.
Who supplies the Universal Ph Indicator?
Science Lab Supplies supplies this indicator paper from Ambala, India, and can quote it with other test papers, glassware and chemicals for the same laboratory.
How should the indicator paper be stored?
Keep it closed, dry and away from light and laboratory fumes. Shelf life depends on storage, so ask for the expiry date of the batch on your quotation.
