Lugols Iodine 3%




This item is restricted from shipping to the U.S.A.

Lugol’s iodine, also known as Lugol’s solution, first made in 1829, is a solution of elemental iodine and potassium iodide in water, named after the French physician J.G.A. Lugol. Lugol’s iodine solution is often used as an antiseptic and disinfectant, for emergency disinfection of drinking water, and as a reagent for starch detection in routine laboratory and medical tests. These uses are possible since the solution is a source of effectively free elemental iodine, which is readily generated from the equilibration between elemental iodine molecules and triodide ion in the solution.

It has been used more rarely to replenish iodine deficiency. However, pure potassium iodide, containing the relatively benign iodide ion without the more toxic elemental iodine, is strongly preferred for this purpose. Likewise, in the Chernobyl disaster some Lugol’s solution was used as an emergency source of iodide to block radioactive iodine uptake, simply because it was widely available as a drinking water decontaminant, and pure potassium iodide without iodine (the preferred agent) was not available.

Please note: Iodine has a tendency to Leech through most containers, this can result in reduced quality of pipette type bottles over time. Due to the nature of the product we unfortunately do not cover replacements for pipettes. However they can be purchased Here
