Handle in a well-ventilated area or a fume hood, wearing nitrile gloves and eye protection. It stains skin, fabric and most surfaces on contact. Store sealed, cool, dark and dry, away from heat, metals, ammonia and reducing agents. Read the Safety Data Sheet in full before opening.\u003c\/p\u003e\n\n\u003ch3\u003eRegulatory notice\u003c\/h3\u003e\n\u003cp\u003eIodine at concentrations above 2.2% is a List I chemical under 21 CFR Part 1310. All sales are recorded, there is no minimum-quantity exemption, and orders may be limited or declined at our discretion. Purchasers are responsible for compliance with federal, state and local law.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\n\u003ch4\u003eAre these iodine crystals or iodine prills?\u003c\/h4\u003e\n\u003cp\u003eCrystals. This is crystalline elemental iodine in its natural flake and shard form, not prilled spheres. If your procedure calls for \"iodine crystals,\" \"resublimed iodine\" or \"elemental iodine,\" this is what you want.\u003c\/p\u003e\n\n\u003ch4\u003eWhat purity is it, and can I get documentation?\u003c\/h4\u003e\n\u003cp\u003e99.99%. A Certificate of Analysis and Safety Data Sheet are available on request — contact us with your order number, or before ordering if your application needs the specifications up front.\u003c\/p\u003e\n\n\u003ch4\u003eIs this the same iodine as your Lugol's Solution?\u003c\/h4\u003e\n\u003cp\u003eIt is the same element, but not the same product. Our Lugol's Solution and Nascent Iodine products are supplement-grade liquids, formulated and labelled for that purpose. This listing is unformulated elemental iodine for laboratory and industrial use only.\u003c\/p\u003e\n\n\u003ch4\u003eHow much can I order?\u003c\/h4\u003e\n\u003cp\u003eSizes run from 7.5 g to 1 kg. Because iodine above 2.2% is federally regulated, we record all sales and may limit or decline orders.\u003c\/p\u003e\n\n\u003ch4\u003eHow should I store it once it arrives?\u003c\/h4\u003e\n\u003cp\u003eKeep it in the sealed container it ships in. Iodine sublimes at room temperature, so a loosely closed container will lose material and stain everything near it. Cool, dark and dry — and never in a metal container.\u003c\/p\u003e","brand":"Lugol's Original's","offers":[{"title":"15 Grams","offer_id":34993735553,"sku":"I2 15 Grams","price":24.99,"currency_code":"USD","in_stock":true},{"title":"7.5 Grams","offer_id":34993735617,"sku":"I2 7.5 Grams","price":19.99,"currency_code":"USD","in_stock":true},{"title":"50 Grams","offer_id":34993735681,"sku":"I2 50 Grams","price":34.99,"currency_code":"USD","in_stock":true},{"title":"100 Grams","offer_id":34993735745,"sku":"I2 100 Grams","price":64.99,"currency_code":"USD","in_stock":true},{"title":"250 Grams","offer_id":34993735809,"sku":"I2 250 Grams","price":139.99,"currency_code":"USD","in_stock":true},{"title":"1000 Grams","offer_id":34993735873,"sku":"I2 1000 Grams","price":699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1997\/7669\/files\/PRILLEDIODINE.png?v=1702923389","url":"https:\/\/www.lugolsnaturals.com\/products\/iodine-crystals","provider":"Lugols Originals","version":"1.0","type":"link"}
