Gram's Iodine Solution, 1 fl oz (30mL) - The Curated Chemical Collection

Worked excellent for testing the purity of my glutathione supplement.

A must, and probably part of the most important staining process, for microbiology research. I use it all the time in determining what ails my family members. It arrived sooner than scheduled and was exactly what it claimed to be! And, the price was right!

I used it in a science experiment in a middle school to show chemical reactions. It worked as advertised.

Worked great just wish it was a dropper bottle so I didn’t have to buy a set of droppers

I used this to demonstrate a diffusion experime t with my biology students and it worked just fine.

I bought this product to stain starch granules for my research. The product works exactly as advertised.

Arrived quickly! Did what I needed it to do.

Product as described (idodine) for testing potency of Mushroom extract. Would have been nice to have a dropper included for dispensing the liquid.
