Universal pH Indicator (Indicator)
Universal pH Indicator (Indicator) (Product Code: SCI-539/233) is a paper test indicator used to estimate the pH of liquids across the full 0-14 scale in school, college and field laboratories. Because it changes through a series of colours rather than giving a simple acid-or-alkali result, students can read an approximate pH value from a single strip. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Universal pH Indicator Paper Used For?
A strip dipped briefly into a solution, or touched with a drop from a glass rod, changes from red through orange, yellow and green to blue and violet as the sample moves from strongly acidic to strongly alkaline. Matching the colour against a pH colour key gives an approximate value, so students can rank vinegar, lemon juice, soap solution and baking-soda solution, test soil extracts or screen water samples. Giving each group its own piece of pH indicator paper lets a whole class in India test samples at the same time.
Compared with litmus, which only shows acid or alkali, universal indicator paper shows how strong an acid or base is, making it ideal for lessons on the pH scale and on neutralisation. When a precise reading is needed, confirm it with a pH meter. Keep the strips dry, handle them by one end with clean, dry fingers or forceps, store them away from acid and ammonia fumes, and never dip the whole pack into a sample.

- Litmus Paper Blue — a simple acid test to compare with the universal paper.
- Litmus Paper Red — a simple alkali test for the same comparison.
- PH Meter 0-14 — gives a precise reading across the same range.
- Universal Indicator Sol — a liquid universal indicator for demonstrations in flasks.
- Acid-Base Environment of the Solution (chart) — a wall chart for teaching acidic, neutral and alkaline solutions.

Frequently Asked Questions
What pH range does Universal pH Indicator (Indicator) cover?
Universal pH Indicator (Indicator) covers the full pH scale from 0 to 14 on paper. One strip can therefore show whether a sample is strongly acidic, weakly acidic, neutral, weakly alkaline or strongly alkaline, instead of the simple two-way result given by litmus.
How is universal indicator paper used?
Dip the end of a Universal pH Indicator (Indicator) strip into the sample for a moment, or touch it with a drop on a glass rod, then compare the colour straight away with a pH colour key. Read it quickly, before the colour shifts as the paper dries.
Is a colour chart included with Universal pH Indicator (Indicator)?
The listing for Universal pH Indicator (Indicator), SCI-539/233, states the paper material and the 0-14 range but does not describe the pack contents. Ask us to confirm the pack form and whether a colour key is included when you request a quotation.
What is the difference between universal indicator paper and litmus paper?
Litmus paper only shows whether a solution is acidic or alkaline, while Universal pH Indicator (Indicator) gives a different colour for each part of the pH scale. It therefore shows how acidic or alkaline a sample is, which litmus paper cannot do.
How should Universal pH Indicator (Indicator) be stored?
Store Universal pH Indicator (Indicator) in a closed container in a cool, dry, dark place, away from laboratory fumes such as ammonia or hydrochloric acid that can discolour unused strips. Shelf life depends on storage conditions, so ask us for the expiry date of the batch you are quoted.
Who supplies Universal pH Indicator (Indicator) in bulk?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, supplies Universal pH Indicator (Indicator) to schools, colleges, water-testing projects and dealers in India and international markets. Send the quantity and destination through the contact page to receive a quotation.
