Product Code : SCL-LC-12195
Aluminium Sulphate (SKU SCL-LC-12195), also spelt aluminum sulfate, is an inorganic aluminium salt used to prepare solutions, study aluminium and sulphate ions, and demonstrate coagulation and flocculation under supervision. School chemistry labs, college practical rooms and analytical laboratories use it. As a laboratory chemicals supplier in India, Science Lab Supplies ships it out of Ambala to schools, colleges, training institutes, tender contractors and distributors.
Specifications
Anhydrous aluminium sulphate is Al2(SO4)3, with a molecular weight of about 342.1 g/mol; hydrated forms such as the octadecahydrate carry water of crystallisation. The material is a white crystalline solid or powder. The hydrate form, grade and net weight supplied are printed on the label and confirmed on your quotation.

Applications and Experiments for Aluminium Sulphate
Dissolved in water, the salt gives aluminium ions that hydrolyse and form flocs, so teachers use it to show how suspended particles are removed from 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 samples.
- Class 12 salt analysis: identifying the aluminium ion and the sulphate ion.
- Environmental engineering practicals such as jar tests on coagulant dose.
- B.Sc. inorganic chemistry work on aluminium salts and hydrolysis.
Dust or solution can 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 listing 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.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Reach the team on the contact page, collect items in the enquiry cart, or see how tenders are handled on the lab tender page.
Frequently Asked Questions
Is this aluminium sulphate suitable for drinking-water treatment?
No. It is listed as 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?
Science Lab Supplies supplies the salt from Ambala, India, to school and college laboratories, tender contractors and distributors, quoting pack size, grade and form for each order.
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.
