Product Code : SCL-LC-12286
Iodine Crystals (SKU SCL-LC-12286) are elemental iodine, I2, a Group 17 halogen for iodine solutions, starch-iodine tests, sublimation demonstrations, redox chemistry and qualitative analysis. The crystals and their vapour irritate skin, eyes and airways, so they suit school and college laboratories where trained staff dispense them. Science Lab Supplies fills orders from Ambala, India, for schools, colleges, tender contractors and distributors, for laboratory use only and never as a medicine or antiseptic.
Specifications
Iodine’s identity, vapour hazard, handling and storage are set out fact by fact in the table. In short, the product is molecular iodine, CAS 7553-56-2, 253.81 g/mol, in crystal form; it gives off irritating vapour, so the container is closed straight after dispensing and any heating happens only in closed apparatus or a fume hood.

Applications and Experiments for Iodine Crystals
The crystals can be used to make iodine solution for starch testing, kept in a Glass Reagent Bottle With Screw Cap, and to show solid iodine turning straight to vapour in a beaker covered with a Watch Glass. Only trained staff should dispense them, with gloves, eye protection and ventilation.
- Class 9 science: sublimation demonstrated by the teacher in closed apparatus.
- Class 10 science (photosynthesis and nutrition): iodine solution for testing leaves and foods for starch.
- Class 12 chemistry (p-block elements): properties of halogens, shown with iodine.
- B.Sc. volumetric analysis: iodine solutions for iodometric and iodimetric titration.
Standard Scope of Supply
The consignment contains one pack of Iodine Crystals with a batch label, the Safety Data Sheet, shelf-life detail and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Grade and pack size are named on the quotation.
Packing, MOQ and Lead Time
Quotations are available for a single pack or a bulk order of school chemistry lab equipment in India, and each lists packing, delivery time and price for that quantity. Potassium iodide and titration reagents can be quoted together so that the iodine solution can be made up on arrival.
Holding an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. Ask about grade or pack size on the contact page, pair the crystals with potassium iodide in the enquiry cart, or use the lab tender page when buying by tender.
Frequently Asked Questions
Are Iodine Crystals hazardous?
Yes. The crystals and vapour can irritate the eyes, skin and respiratory system. Use gloves, eye protection and ventilation, keep the container closed, and never heat iodine in open air.
Can the crystals be used in school labs?
Yes, in supervised school and college laboratories where trained staff control dispensing, demonstrations, storage and ventilation. Students should work only with prepared, labelled solutions.
Who supplies the Iodine Crystals?
Each pack is batch-labelled and sent by Science Lab Supplies from Ambala, India, together with its Safety Data Sheet and the transport documents.
Can Iodine Crystals be used as an antiseptic or medicine?
No. These crystals are for laboratory use only. They must not be used as a medicine, antiseptic, disinfectant, supplement or water-treatment chemical.
