Shap Alumini
Shap Alumini (Product Code: SCI-740/325) is an analytical reagent grade aluminium alum, a double sulfate salt used for crystal growing, water-clarification demonstrations and double-salt tests in school and college chemistry laboratories. It is supplied with its MSDS; the listing does not state a pack size, so confirm the quantity and the exact alum (commonly potash alum) when you enquire. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its school chemistry lab equipment and reagent supply.

What Is Shap Alumini Used For?
Alum is the classic salt for growing large, clear octahedral crystals: a seed crystal hung on a thread in a saturated, slowly cooling solution keeps growing over several days, a memorable project on crystallisation and saturation. In senior practicals, potash alum is prepared from aluminium sulfate and potassium sulfate, and a solution of the product gives the separate tests for potassium, aluminium and sulfate ions, showing that a double salt dissociates fully in water.
Stirring a little alum into muddy water makes the fine particles clump together and settle, a simple demonstration of the coagulation step used in water treatment. Alum is also a traditional mordant that helps dyes bind to cotton and wool in dyeing experiments. Handle it with normal laboratory care, avoid eye contact and follow the MSDS.
What to Specify When Ordering
- The quantity you need, since the listing does not give a pack size.
- Which alum you mean (potash alum or ammonium alum), so the right salt is quoted; Potash Alum also has its own listing.
- The main use (crystal growing, water clarification or double-salt tests) and any companion salts such as aluminium sulfate or potassium sulfate.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, and the company supplies Shap Alumini from Ambala with its MSDS to schools, colleges and teacher-training laboratories. Because this salt is sold under several names, we confirm the exact alum and quantity before quoting for institutions, dealers and importers in India and international markets. See the ScienceLab profile for more about the company.

Frequently Asked Questions
What is Shap Alumini?
Shap Alumini SCI-740/325 is a catalogue name for aluminium alum, a double sulfate salt; the common laboratory form is potassium aluminium sulfate, known as potash alum. It is analytical reagent grade and supplied with its MSDS, so confirm the exact alum when you enquire.
How do you grow alum crystals with Shap Alumini?
Dissolve Shap Alumini in hot water until no more dissolves, let the solution cool, then hang a small seed crystal on a thread in the clear liquid. Covered and left undisturbed, the seed grows into a large octahedral crystal as the water slowly evaporates.
What pack size is Shap Alumini supplied in?
The Shap Alumini listing (SCI-740/325) does not state a pack size. Tell us the quantity you need for crystal growing, water-treatment demonstrations or double-salt practicals through the contact page, and we will confirm what can be supplied before quoting.
How should Shap Alumini be stored?
Keep Shap Alumini SCI-740/325 in a closed container in a cool, dry place so the crystals stay in good condition. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Shap Alumini SCI-740/325?
Shap Alumini SCI-740/325 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and provides it with its MSDS to schools, colleges, dealers and importers in India and international markets.
What does a Shap Alumini quotation need?
A Shap Alumini quotation needs the product code SCI-740/325, the quantity, which alum you require and your delivery location. Send these through the contact page or the enquiry cart, and add any aluminium or potassium sulfate you need for alum preparation.
Request a Quote
Request Shap Alumini through the ScienceLab contact page or add it to the enquiry cart, stating the quantity and which alum your crystal-growing or water-treatment lessons need.
