Paper, Universal
Paper, Universal (Product Code: SLE/CH/213) is a universal indicator paper covering pH 1 to 11. Unlike litmus, which only says acid or alkali, it turns a different colour at different points of the scale, so students can estimate how acidic or alkaline a solution is in a few seconds. It comes as a plastic case of 10 books, each holding 20 leaves, which suits school practical classes, college chemistry and biology labs, and quick checks on water or soil extracts. Schools and colleges sourcing pH indicator paper in India can order it from Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, which supplies it alongside its own laboratory equipment.

Typical Use
In a classroom, a teacher can hand each group a single book and ask them to test vinegar, lemon juice, soap solution, tap water and a soil extract, then arrange the samples in order from most acidic to most alkaline. The paper is also handy for checking that a neutralisation is complete, for showing that some salt solutions are not neutral, and for rough pH checks in plant and microbiology practicals. Because it is one of the most frequently reordered chemistry consumables, many labs keep a case in each practical room.
For a clean reading, tear off one leaf, place a drop of the sample on it with a glass rod rather than dipping the whole leaf, and compare the colour with the pH colour reference straight away, before the strip dries. Since the scale stops at pH 11, strongly alkaline solutions such as dilute sodium hydroxide will simply show the top colour; for those, a full-range paper is the better choice. Keep the case closed between uses so the books are not exposed to acid or ammonia fumes.
Supplier
This indicator paper is supplied, not manufactured, by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades under the ScienceLab name. Schools and colleges can order it together with the glassware and apparatus the company makes, so one enquiry covers a full practical set-up.

- Paper, Universal, pH 1-14 — the full-scale version for samples that are strongly alkaline.
- pH Indicator Dispenser — a continuous strip you tear to length, useful at a shared bench.
- Red Litmus Paper — a quick first screen for alkalis before estimating pH.
- Blue Litmus Paper — the matching first screen for acids.
- Stirring Rod, Glass — transfers a single drop to the leaf so the rest of the book stays dry.

Frequently Asked Questions
What pH range does this paper cover?
It covers pH 1 to 11. If your samples include strong alkalis above that range, choose the full-scale pH 1-14 paper listed above.
How much paper is in one case?
One plastic case holds 10 books, and each book contains 20 leaves, so a single case can be split between several student groups.
How do I read the result?
Wet the leaf with a drop of the sample and compare its colour with the pH colour reference immediately. If you need to know the format of the colour reference supplied with current stock, please ask us through the contact page.
Can it replace a pH meter?
For approximate readings in teaching labs, yes. Where a precise numerical value is required, for example in research or quality testing, a calibrated pH meter is the right tool.
How should the books be stored?
Keep them closed inside the plastic case, in a dry place away from sunlight and chemical fumes, and handle leaves with dry fingers or forceps to avoid false colours.
Do you supply larger quantities for institutions or export?
Yes. We supply schools, colleges and distributors across India and international markets. Share the product code SLE/CH/213, the number of cases and the delivery location, and we will prepare a quotation.
