Iodine Crystals
Product Code : SCL-LC-12286
Iodine Crystals (SKU SCL-LC-12286) are elemental iodine, I2, a Group 17 halogen used for iodine solutions, starch-iodine tests, sublimation demonstrations, redox chemistry and qualitative analysis. School science teachers and college chemistry staff dispense it under supervision because the crystals and vapour irritate skin, eyes and airways. Science Lab Supplies dispatches it from Ambala, India, to schools, colleges, tender contractors and distributors, for laboratory use only and never as a medicine or antiseptic.
Specifications
The product is molecular iodine in crystal form. It gives off vapour, so the container is closed immediately after dispensing and any heating is done in closed apparatus or a fume hood. Grade, assay, crystal form and pack size are stated on the quotation and batch label.

Applications and Experiments for Iodine Crystals
Teachers use the crystals to make iodine solution for starch testing, to show solid iodine turning straight to vapour in a closed setup, and to teach halogen and iodide-iodine chemistry. Only trained staff should dispense them, wearing gloves and eye protection, working with ventilation and collecting residues as chemical waste.
- 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 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. Get in touch through the contact page, compile items in the enquiry cart, or read the lab tender page for tender enquiries.
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?
Science Lab Supplies supplies them from Ambala, India. Each pack carries a batch label and is sent with its Safety Data Sheet and transport documents.
Can Iodine Crystals be used as an antiseptic or medicine?
No. This listing is for laboratory-use iodine only. It must not be used as a medicine, antiseptic, disinfectant, supplement or water-treatment chemical.
Related Halogen and Sublimation Reagents
Iodine practicals rely on a few companion chemicals: an iodide to dissolve it, a titrant, another halogen for comparison and a second substance for sublimation lessons. These four items from the same Lab Chemicals range can share one quotation with the crystals.
- Potassium Iodide — iodide salt for preparing iodine solution.
- Sodium Thio Sulphate — reagent for iodometric titration.
- Bromine Water — aqueous bromine for halogen chemistry.
- Ammonium Chloride — ammonium salt for sublimation demonstrations.
