any relativly simple way to make it?

as my only source atmo is 3% contact lense cleaner, and that's expensive as hell.

nope, and you`ll be very disappointed to note that making it is even more Expensive than hell!

 

if a factory plant knocks the stuff out at their price, what chance have you got to make it cheaper? LOL

 

and yes, I`ve looked into myself in the past, give up now, while you still have Cash in the bank, be happy with your 3%

the stuff from the store is 3% and costs 79 per a pretty big bottle,

Is there a way of concentrated that amount? By perhaps freezing or boiling off the water/ H2O2 ?

yes.

During all this year I've been working with H2O2 in research of his oxidation power and countless times I've been told to be really carefull with this stuff, the one I'm using is 30%w/v, about 8.8Molar, and seems to be really really expensive. If someone knows a non-expensive way to producing it just tell me .

didn`t you read post #2?

Its pretty easy to purify it by freezing but not very efficient, and when I say not very I mean not at all. It's still entertaining though.

using our search facility will answer ALL of these questions too, it`s not like this topic hasn`t been covered a few 100 times before *Yawn*

And we came to the same conclusion that YT did in post #2.... well, I spose we went into a few pages more details and sidetracks...

The last sentence of my post was ironic, of course I've read post#2, because of that reason I've put that icon ( ). It was Just an irony.

ok, cheers.

 

it just seems so overpriced, like £2(3.5$) for 300ml 3% solution.

oh well, i'll try and find some 30% stuff as pool cleaner.

it costs 79 cents for 300-400ml bottle here

so, working on organic peroxides, are we? dont die or anything

me? im not

it will be, don`t forget to be used for contact lens soln, it`s purity must me no less than 100%, and that`s what you`re paying for. I have a saline soln in an aerosol that was for contact lenses, who`d have thought salt water would cost nearly a fiver!
