Guest guest Posted January 20, 2012 Report Share Posted January 20, 2012 Hi,I am looking at purchasing a 4 oz bottle of Lugol's 2% through one of the eBay seller recommended on this loop. I am figuring correctly that a 4-oz bottle would have apx 3,140 drops equaling apx 7850mg of iodine? Thank you. in Alaska Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 20, 2012 Report Share Posted January 20, 2012 : Not sure where you're starting with your calculations, but they don't look quite correct to me. Generally, the mg-per-drop figure quoted is based on the assumption that the dropper you'll be using, heheld straight up and down, delivers a single drop that is approx. 1/20 of a milliliter. Given that assumption, Lugol's 2% contains roughly 2.5 mg iodine per drop. There are 30 ml in a fluid ounce, thus, 600 drops per ounce or 2400 drops in a 4 ounce bottle. All of which is a variable estimate, given evaporation from the bottle over time, variable droplet size, etc., but 2400 is probably a reasonable guesstimate. 2400 x 2.5 = 6000 mg of iodine. More or less. Trust this helps. Regards, Megaera > > Hi, > > I am looking at purchasing a 4 oz bottle of Lugol's 2% through one of the > eBay seller recommended on this loop.

Guest guest Posted January 20, 2012 Report Share Posted January 20, 2012 Hi Megaera,I was basing my apx on the statement on this eBay listing. " Each full eyedropper (approximately .75 milliliters) contains 16.5 milligrams of iodine and 33 milligrams of potassium iodide. Total iodine per drop is approximately 2.55mg. " With each ounce having 30ml, that would make 160 dropperfuls (.75ml) per 4 ounce bottle for a total of 8000mg of iodine per bottle. The only difference was I used .75ml per dropperful vs 1ml per dropperful making a difference of 120 dropperfuls vs 160 dropperfuls, thus 6000mg vs 8000mg. I just wanted to make sure I was on the right track in my figuring.Thanks much.On Fri, Jan 20, 2012 at 5:13 PM, Megaera3 <megaera3@...> wrote: : Not sure where you're starting with your calculations, but they don't look quite correct to me.
