Iodine Crystals

Product Code : SCL-LC-12286

The Iodine Crystals Lab Chemical is an elemental halogen reagent used for supervised chemistry experiments, iodine solution preparation, starch-iodine testing, sublimation demonstrations, redox chemistry, and qualitative analysis. It is suitable for schools, colleges, chemistry laboratories, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Iodine Crystals from Science Lab Supplies are intended for controlled educational and laboratory use where elemental iodine is required. The exact grade, assay, pack size, crystal form, batch number, shelf life, SDS, COA, and transport documents must be confirmed before publication or quotation.

Iodine is commonly represented as I₂. In teaching laboratories, it supports lessons on halogens, iodine vapour, sublimation, starch testing, iodide-iodine chemistry, redox systems, and qualitative reagent preparation where the syllabus, SOP, and SDS permit. This page describes laboratory-use iodine only, not pharmaceutical, antiseptic, supplement, disinfectant, water-treatment, or consumer use.

Key Features

• Elemental iodine reagent: suitable for supervised chemistry teaching and approved laboratory procedures.
• Formula reference: iodine crystals are represented as I₂.
• Halogen chemistry support: useful for teaching Group 17 elements, iodine reactions, and iodide-iodine systems.
• Sublimation demonstration value: supports approved closed-apparatus demonstrations of solid-to-vapour behaviour.
• Starch testing support: can be used for approved iodine solution preparation where the SOP permits.
• Pack size verification: supplied quantity and container type must be confirmed from the final quotation.
• Documentation-led procurement: SDS, COA, assay, batch number, and shelf-life details should be verified before use.

How to Use the Iodine Crystals

1. Read the current SDS, product label, and institutional risk assessment before use.
2. Allow only trained laboratory personnel to dispense iodine crystals.
3. Wear suitable PPE, including lab coat, compatible gloves, and eye or face protection.
4. Work in a fume hood or approved ventilated area if vapour, dust, heating, or solution preparation is involved.
5. Use only the minimum quantity required by the approved laboratory procedure.
6. Measure crystals with clean, dry, compatible tools and close the container immediately after dispensing.
7. Prepare iodine solutions only in labelled containers using the written institutional method.
8. Collect residues and contaminated materials according to institutional chemical-waste procedures.

Safety note: Iodine Crystals must be handled as a hazardous halogen reagent. Do not inhale vapour, touch with bare hands, heat in open air, ingest, use medically, or issue for unsupervised student handling.

Care & Maintenance

• Store tightly closed in a cool, dry, ventilated and restricted chemical-storage area.
• Keep away from incompatible chemicals, reducing agents, ammonia-containing materials, food items, and unlabelled containers.
• Minimise unnecessary opening because iodine can release irritating vapour.
• Maintain SDS, COA, batch number, grade, pack size, and shelf-life records for audit control.

Frequently Asked Questions

What are Iodine Crystals used for in a laboratory?

Iodine Crystals are used as an elemental iodine reagent for supervised chemistry teaching, iodine solution preparation, starch-iodine testing, sublimation demonstrations, and approved qualitative analysis.

What is the formula of Iodine Crystals?

The formula of molecular iodine is I₂. Its CAS number is 7553-56-2 and its molecular weight is 253.80894 g/mol.

Are Iodine Crystals hazardous?

Yes. Iodine crystals and vapour can irritate the eyes, skin, and respiratory system. SDS-based handling, PPE, ventilation, restricted access, and controlled disposal are required.

Can Iodine Crystals be used for school chemistry labs?

Yes, but only for supervised school and college chemistry laboratories where trained staff control dispensing, demonstrations, storage, ventilation, and disposal.

What grade is supplied?

The grade is not confirmed. Add LR, AR, ACS, resublimed, analytical, technical, assay, or purity details only after verifying the product label, COA, or datasheet.

Can Iodine Crystals be used as medicine or antiseptic?

No. This page describes laboratory-use Iodine Crystals only. It should not be marketed or used as medicine, antiseptic, disinfectant, supplement, water-treatment chemical, or consumer product.
