Dosing Lugol's Iodine- need advice on replacement pasteur pipette

SuperNerd · 03/13/2008, 03:05 PM

The warner marine dropper/pasteur pipette I was using has cracked and now I need to find another one. What type of dropper should I use as a replacement?

I know this wasn't the question, but I don't recommend any iodine supplements as I do not believe them useful, and for those who want to dose anyway, I recommend iodide, not I2 solutions, since the I2 is reactive and unnatural. The dropper may have cracked due to the reactivity of the I2.

That said, what sort of droppers do you have available? Polyethylene droppers would be fine, as would glass.

Hi Randy. Thank you for replying. I only have the pipettes that come in the Salifert test kit boxes. Are the "drops" of all pasteur pipettes basically the same in size?

They may vary a bit based on the actual size of the tip.
