iodine - PLEASE HELP

[beesley121]

Hi guys,

I purchased a bottle of iodine from my LHBS and Ive misplaced the instructions on how to use it.

can someone tell me how to prepare a solution that can be used in a spray bottle to effectivly sanatize equipment;. Also im on the understanding that this is a no rinse product.

can u help

If it is iodine (tincture) it can't be used for sanitation . . . if it is iodophor then it can

Here you go.

I just made up some Videne for the first time, using acidified tap water as per DaaB's recipe above, but I was also trying-out my pH meter ditto. Brupaks Iodophor is supposed to be acidified already, if that's what you got from the HBS.

I put 1ml from a syringe into 500ml of water, which with Videne (1% free iodine) should give about 20 parts per million as a no-rinse solution. It's gone into a 50p garden sprayer from Wilco's.

I think mine is the brupaks iodophor. not quite sure where I bought it but think it was from 'the home brew shop'. All I can remember is the it came in see through bag with the instrictions on a piece of paper, not stuck on the bottle. hence why I have lost the instructions!!!

Anyways, made it up as per daabs recipe, 0.6ml per litre and I must say the resulting product looks very weak. I can only just see a taint of the iodophor in it when I pour some into a glass.

have I done this right?? dont want to waste a brew

Et voila:



The Kodak scales might help, though there's some flare from the camera flash

defo not that colour.

i think I have just found a pic on another site and can read the instructions on the pack!! it say half a teaspoon per litre.

is that the same as 0.6ml per litre

[edit1now]

Standard teaspoon is 5 ml, so half = 2.5ml?

[beesley121]

so should I go for that then as a non rinse sanatiser!!

just dont under stand why the instructions say 2.5ml per litre and daab say 0.6ml per litre

its defo the brupaks iodophor that im using

2.5 millilitres is the official proper, full-strength concentration (should be rinsed).
0.6ml in the unofficial, no-rinse concentration.
I have not done the sums myself, but I assume that Daabs figures were for Brupaks iodophor. Iodophors vary in strength, and Brupaks is stronger than most, I think.
