Tetenal E6 avaialble in USA again

[Tony-S]

As far was where to buy it; try a scientific or biologic supply company. I work in a research lab and we buy it all the time in gallon jugs. I am sure fisher scientific will supply in smaller amounts.

Formalin is generally difficult to obtain without a proper relationship between the seller and buyer (such as a diagnostic laboratory) because of the hazardous nature of the chemical.

I buy it on ebay. Not too hard at all.

Formalin is not even remotely hard to buy. Do a search on Amazon and you will immediately turn up multiple sizes and sources of 10%. PE says this is fine to use as long as proportions are adjusted accordingly. 37% is rare for reasons mentioned above, but you don't need that.

And you're certain that 10% buffered formalin will not screw up the film?

I asked PE the same thing, WRT some 10% I found on eBay. Question here:

I know the link will go away so here it is in English. $4.66 for 500ml. Shipping from the UK to the USA is an extra $13.23. So you see you can even get it shipped across the pond with little effort and expense. Also remember DO NOT STOCK UP. It goes bad so there is no point in buying too much.

How long does it last in it's sealed container?
I have 37% formalin.

So, can the 5 liter Tetenal kit be mixed 1 liter at a time, or does oxidation cause problem with the stock chems?

Yes, no problem. The concentrates last 6 months once opened, so assuming you use it within that period, you should be fine, and will save a lot over the 1L kit.

That's still a lot of film in six months!

OTOH, my experience with other brands of E6 liquids years ago (Unicolor) was that it lasted a good bit longer than they said, if you just squeezed all the air you could out. I kept the stuff a year, which was just about time enough to use up a gallon, with no problems. I suspect the Tetenal would, in practice, keep as well.
