Test Paper Books
Product Code : LSK-CL-10079
Test Paper Books (SKU LSK-CL-10079) are booklets of chemically treated indicator paper for quick tests in the chemistry laboratory. They come in seven types: cobalt chloride, lead acetate, blue, neutral and red litmus, pH 1–14 universal, and starch-iodide. A strip touched to a liquid or held in a gas shows the result by a colour change. Laboratories, schools, colleges, tender contractors and distributors can source the books through Science Lab Supplies, which quotes and dispatches them from Ambala, India.
Specifications
Each of the seven paper types in the test paper range has its own row below. In short, litmus and universal papers show acidity or alkalinity, while cobalt chloride, lead acetate and starch-iodide papers detect specific substances, so a laboratory can choose only the types its practicals need.

Applications and Experiments for Test Paper Books
The books are used wherever a fast qualitative result is needed: testing acids and bases, checking the pH of solutions and soils, and identifying gases or water in practical work. They support NCERT Class 7 and 10 acids, bases and salts, Class 11–12 qualitative analysis, and B.Sc. laboratory courses.
- Class 7 and 10 science: classifying household substances as acidic, basic or neutral with litmus, alongside The Acid-Basic Environment of The Solution wall chart.
- Class 11–12 salt analysis: lead acetate paper for sulphide and starch-iodide paper for oxidising gases.
- Confirming water as a product of combustion or dehydration with cobalt chloride paper.
- Solution pH: a quick universal-paper reading first, then the Bench Digital Ph Meter where a 0.00–14.00 pH value is needed.
Lead acetate and cobalt chloride are toxic compounds. Handle these papers with forceps or gloves under teacher supervision, keep them away from food, and dispose of used strips according to your laboratory rules.
Standard Scope of Supply
Test Paper Books are supplied in the seven types shown in the table. Tell us which types and how many books of each you need, and the quotation will set them out line by line.

Frequently Asked Questions
Which types of test paper books are available?
Seven types: cobalt chloride, lead acetate, litmus blue, litmus neutral, litmus red, pH 1–14 universal and starch-iodide. Order only the types your practicals use.
Are any of these papers hazardous?
Yes. Lead acetate and cobalt chloride papers contain toxic compounds, so students should handle them under supervision, avoid skin contact and dispose of used strips safely.
How long do the test papers keep?
Shelf life depends on the chemical, its grade and storage conditions. Store the books closed, dry and away from fumes, and ask for the expiry date of the batch quoted.
Who supplies the Test Paper Books?
Quotations come from Science Lab Supplies in Ambala, India, for schools, colleges, laboratories and distributors, and can cover a handful of books of one type or a mixed bulk lot of all seven.
