Calcium Sulphate Anhydrous Scientific Reagent Manufacturer,Supplier and Exporter in India

Product Code : SCL-CA-12656

The Calcium Sulphate Anhydrous is an inorganic calcium sulfate reagent used for controlled sulphate-salt studies, drying-support demonstrations, solution-comparison work, and supervised chemistry-lab procedures. It is suitable for trained chemistry teachers, laboratory technicians, authorised school and college laboratories, distributors, and procurement teams requiring verified reagent identity, SDS review, and dry powder handling.

Product Description

Calcium Sulphate Anhydrous from School Equipments India is prepared for the laboratory chemicals, chemical-analysis reagents, and inorganic sulphate salts category. A direct verified product page for this exact chemical was not found, so grade, assay, particle form, pack size, container type, SDS, COA, batch number, and expiry or retest date must be confirmed before catalogue upload or ordering.

Calcium sulphate is also written as calcium sulfate. The anhydrous form has the formula CaSO₄ and CAS number 7778-18-9. It should not be confused with gypsum, the dihydrate form, or plaster of Paris, the hemihydrate form. Hydration state affects formula weight, drying behaviour, and calculation accuracy.

Key Features

• Anhydrous calcium sulfate identity: suitable for procedures where water-free CaSO₄ is specified..
• Formula CaSO₄: useful for stoichiometry, salt-composition lessons, and formula-mass calculations.
• White solid format: practical for weighing, dispensing, and controlled demonstration use.
• Dry-storage requirement: keep tightly closed to protect material condition and minimise moisture exposure.
• Dust-control handling: avoid inhaling fine particles during transfer, weighing, and cleanup.
• Procurement-safe listing: unverified pack size, assay, particle form, and documents are marked for confirmation.

How to Use the Calcium Sulphate Anhydrous

1. Read the current SDS, COA, product label, and laboratory risk assessment before use.
2. Confirm grade, assay, particle form, and method suitability before weighing or dispensing.
3. Wear safety goggles, suitable gloves, and a lab coat before handling.
4. Use a clean, dry spatula and take only the quantity required by the approved procedure.
5. Avoid generating dust during transfer, weighing, mixing, and cleanup.
6. Keep the container closed immediately after use to minimise moisture exposure.
7. Label prepared mixtures or containers with name, date, preparer, and relevant hazard information.
8. Dispose of residues according to institutional chemical-waste procedures.

Safety note: Calcium sulphate anhydrous dust may cause mechanical irritation. Students should use it only under trained teacher or laboratory-technician supervision with eye protection, dust control, and current SDS access.

Care & Maintenance

• Store tightly closed in a dry, labelled chemical-storage area.
• Keep away from moisture, food items, incompatible materials, and unauthorised users.
• Use clean and dry dispensing tools to prevent contamination and moisture carry-back.
• Dispose of contaminated, unlabelled, or expired reagent through approved laboratory procedures.

Frequently Asked Questions

What is Calcium Sulphate Anhydrous used for?

Calcium Sulphate Anhydrous is used for authorised sulphate-salt studies, calcium-salt demonstrations, formula-mass calculations, drying-support demonstrations, and chemistry procedures where anhydrous CaSO₄ is required.

What is the CAS number of calcium sulphate anhydrous?

The CAS number of calcium sulphate anhydrous is 7778-18-9. This number should be used to match the SDS, COA, product label, and procurement record.

What is the formula of calcium sulphate anhydrous?

The formula of calcium sulphate anhydrous is CaSO₄. Its molecular weight is about 136.14 g/mol.

Is calcium sulphate anhydrous the same as gypsum?

No. Calcium sulphate anhydrous is CaSO₄, while gypsum is the dihydrate form, CaSO₄·2H₂O. Hydration state should be confirmed before ordering.

Is Calcium Sulphate Anhydrous suitable for school laboratories?

Yes, it can be used in supervised school and college laboratories when teachers or technicians control PPE, weighing, dust prevention, labelling, storage, and disposal.

What documents should be confirmed before ordering?

Confirm the SDS, COA, grade, assay, pack size, batch number, expiry or retest date, label details, particle form, and final packaging before ordering.
