Product Code : SCL-LC-12193
Barium Sulphate (SKU SCL-LC-12193), also written barium sulfate (BaSO4), is a white or yellowish inorganic barium salt of low solubility. It can be used to teach insoluble sulphate salts, as reference material where an approved method names it, and in supervised school, college and analytical practicals. Science Lab Supplies sends this reagent out from its Ambala base in India to schools, colleges, analytical laboratories and distributors that request a quotation.

Applications and Experiments for Barium Sulphate
Barium sulphate illustrates insoluble salts: students can compare it with soluble sulphates, watch it settle from suspension and relate it to the white precipitate seen in sulphate tests. In colleges and analytical labs it can also serve as reference material where an approved method names barium sulphate.
- Class 10 chemistry: double-displacement and precipitation reactions that produce barium sulphate.
- Class 11–12 salt analysis: recognising the white sulphate precipitate, which can be collected on 120 mm Filter Paper.
- B.Sc. inorganic practicals on solubility, settling and suspension behaviour.
- Training in weighing, dust control and reagent labelling with a porcelain Spoon-Spatula and a 200 g Chemical Semi-Analytical Balance.
Standard Scope of Supply
You receive the barium sulphate container in the quoted pack size, a label giving batch, grade and hazard details, the Safety Data Sheet, and outer packaging with a tamper seal and export papers. 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
Ask for a single pack or stock for several laboratories; the quotation sets out packing, delivery time and price for exactly that quantity. Barium chloride or other salts for sulphate practicals can be quoted together, which keeps an order for school chemistry lab equipment in India on one document.
Holding an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Prices for one pack or a full stock list follow once you write via the contact page or drop the item into the enquiry cart; institutional bids go through the lab tender page.
Frequently Asked Questions
Can this barium sulphate be used for medical imaging?
No. It is supplied as a laboratory reagent only. Do not use it for medical imaging, food, pharmaceutical or cosmetic purposes unless the grade and regulatory status have been verified for that use.
Is barium sulphate hazardous?
Handle it as a laboratory chemical: avoid breathing the dust, prevent eye contact and ingestion, and wear gloves, eye protection and a lab coat. Dispose of residues under your rules for barium-containing waste.
Who supplies the Barium Sulphate?
From Ambala in India, Science Lab Supplies quotes this low-solubility barium salt with the rest of its lab-chemical range for schools, colleges, analytical laboratories and distributors, naming pack size and grade on each quotation.
Can schools use barium sulphate?
Yes, but only in authorised school and college laboratories under trained supervision, following the current Safety Data Sheet and the institution’s chemical-safety procedure for weighing, dust control and storage.
