Been looking everywhere for iodine but can't find the solution anywhere? Is it sold in the uk? I moved over here not long ago and used to get big bottles of the solution to mix up myself..all I can find is the pre-mixed iodine spray in robinsons..

these are iodine crystals, you just measure and mix to whatever molarity solution you want (they can be a ****** to dissolve though but they do eventually)

As long as it's less than a couple of millimolar! It isn't very soluble in pure water, which is why it's often available as a tincture (dissolved in alcohol). The solubility in water can also be increased greatly by adding a little potassium iodide.

May I ask OP what the intended use is? The reason I ask is that elemental iodine and concentrated solutions are pretty corrosive and therefore may not be suitable for treating wounds, even though it is an effective antiseptic. For example, it is (or at least used to be) very common to dip a foal's umbilical cord in iodine solution after separation. More recently vets (Derek Knottenbelt was one I heard describe this) caution against this because the iodine can delay healing, and suggest using chlorhexidine solution instead. Using it to treat thrush would be a different matter.

ETA: Elemental iodine (the crystals) is pretty nasty stuff, as it gives off corrosive vapour.
