Universal pH Indicator
Universal pH Indicator (Product Code: SCI-847/135) is a universal indicator test paper used to estimate how acidic or alkaline a liquid is in school, college and field laboratories. It covers the full pH 0–14 scale, so one piece of paper separates strong acids, weak acids, neutral liquids and alkalis by colour instead of giving only an acid-or-base answer. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as pH indicator paper for teaching labs.

What Is Universal pH Indicator Paper Used For?
A small piece of the paper is touched with a drop of the test liquid on a glass rod, and the colour that develops is compared with a pH colour chart to read an approximate value. Classes use it to rank vinegar, lemon juice, soap solution and baking-soda water along the 0–14 scale, to follow a neutralisation as acid is added to alkali, and to check soil extracts or pond water in environmental projects.
Avoid dipping a whole strip into small samples or stock bottles, because indicator dye can leach into the liquid; tear off only what is needed and keep the rest closed away from acid and ammonia fumes. For acid-base indicator practicals that need a precise number rather than a colour estimate, a pH meter is the better tool.

Frequently Asked Questions
What pH range does the Universal pH Indicator cover?
The Universal pH Indicator SCI-847/135 covers pH 0 to 14, the full scale used in school chemistry, so a single paper shows whether a sample is strongly acidic, weakly acidic, neutral, weakly alkaline or strongly alkaline.
How is Universal pH Indicator paper different from litmus paper?
Universal pH Indicator paper gives a range of colours across pH 0–14 and so estimates the pH value, while litmus paper only shows acid or base. Many labs keep both: litmus for quick checks and the Universal pH Indicator for graded readings.
Is a colour chart included with the Universal pH Indicator?
Whether a colour chart comes with the Universal pH Indicator SCI-847/135 should be confirmed on your quotation. Ask through the contact page and we will state exactly what is supplied with each pack.
How should Universal pH Indicator paper be stored?
Store the Universal pH Indicator in its closed pack, dry and away from strong light and laboratory fumes, which can discolour the paper. Shelf life depends on storage conditions; ask us for the expiry date of the batch you are quoted.
Is a pH meter more accurate than Universal pH Indicator paper?
Yes. Universal pH Indicator paper gives a quick visual estimate, while a calibrated pH meter reads the value electronically. For class demonstrations the paper is usually enough; for quantitative projects, add a pH meter to your enquiry.
Who supplies the Universal pH Indicator SCI-847/135?
The Universal pH Indicator SCI-847/135 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and dealers in India and international markets. Send your quantity and delivery location for a quotation.
