Product Code : SCL-LC-12195
Aluminium Sulphate (SKU SCL-LC-12195), also spelt aluminum sulfate, is an inorganic aluminium salt for preparing solutions, studying aluminium and sulphate ions, and demonstrating coagulation and flocculation under supervision. It suits school chemistry labs with trained supervision, college practicals and analytical laboratories. Science Lab Supplies, a laboratory chemicals supplier in India, prices and dispatches it from Ambala for institutions, tender contractors and distributors.
Specifications
The aluminium sulphate table gives each fact its own row, including both formulas, the anhydrous CAS number and the hazard notes. In short, it is a white crystalline solid or powder; the anhydrous salt weighs about 342.1 g/mol, and the hydrate form, grade and net weight are printed on the label and confirmed on your quotation.

Applications and Experiments for Aluminium Sulphate
Dissolved in water, the salt releases aluminium ions that hydrolyse and form flocs, so it can show how suspended particles settle out of turbid water. It also serves salt-analysis teaching, solution-preparation exercises and analytical or research methods that call for a documented aluminium salt.
- Coagulation and flocculation demonstrations with turbid water in graduated Chemical Glasses (Beaker) 250ml.
- Class 12 salt analysis: identifying the aluminium ion and the sulphate ion.
- Environmental engineering practicals such as jar tests on coagulant dose, with water measured in a glass Measuring Cylinder 250ml.
- B.Sc. inorganic chemistry work on aluminium salts and hydrolysis.
Dust or solution may irritate the eyes, skin and respiratory tract, so wear gloves and eye protection and avoid breathing dust while weighing.
Standard Scope of Supply
Each consignment includes the aluminium sulphate container in the quoted pack size, a label giving batch, grade and hydrate form, the Safety Data Sheet, and outer packaging with a tamper seal and export documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Quotations cover any quantity, from a single pack to supplies for many classrooms, and each states the packing, delivery time and price for what you request. Other salts and chemistry lab equipment in India can be added to the same quotation.
With an Importer-Exporter Code in place, Science Lab Supplies can ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Send the hydrate form and quantity you want through the contact page, or place the salt in the enquiry cart; school and college tenders are explained on the lab tender page.
Frequently Asked Questions
Is this aluminium sulphate suitable for drinking-water treatment?
No. It is a laboratory reagent for teaching and analytical work. Do not use it for water treatment, food, medical or agricultural purposes unless its grade and regulatory status are verified for that use.
Which hydrate form is supplied?
Aluminium sulphate exists as the anhydrous salt and as hydrates such as the octadecahydrate. The form in your batch is shown on the label and quotation, which matters when you calculate solution strengths.
Who supplies the Aluminium Sulphate?
The salt is offered by Science Lab Supplies in Ambala, India, to school and college laboratories, tender contractors and distributors, with pack size, grade and hydrate form spelled out on each quotation.
How should it be stored?
Keep the container tightly closed and clearly labelled in a dry chemical store, away from moisture and incompatible substances, and use clean dry tools so the salt does not cake or become contaminated.
