Pre-mixed fixers available for use with pyro developers

[2F/2F]

Hello,

I got some Formulary liquid PMK developer today, but I think I accidentally grabbed the wrong fixer. I got TF-5 instead of TF-4.

Will it work? Does the fixer for PMK need to be alkaline, or does it just need to be non hardening?

Aside from the Formulary products, are there any pre-mixed fixers on the market that are suitable for PMK pyro?

Eco Pro has a "Neutral Fixer" that the staff at Freestyle said might be an option. However, they were not too sure, so they suggested that I look online.

If I got the wrong one, I cannot think of a better place to have got it. All I have to do is go in and Freestyle will gladly make the hassle-free exchange.

Thank you in advance for your help.

I am pretty sure that the Formulary tested TF-5 with the PMK developer. You might call and ask them first.

either one will work with PMK, if you need more stain, dip film in the used developer for a minute or so after fixing.

It does not "need" to be alkaline in order to do its work, I've used either pyro and catechol with neutral and acid fixers, the main difference seems to be in the stain intensity, which is better with neutral-alkaline ones without sodium sulfite. Ideally there shouldn't be any acid in the process for maximum stain.

TF-5 is the up-dated version of TF-4, and will work perfectly well with any B&W film. When I'm finished with my bottle of TF-4 I'm buying the TF-5. The only difference between the two is the 5 doesn't have to be shaken to remix the solution, making it more convenient to use. You didn't make any mistakes.

What he said.

PE gave a detailed discussion about the advantages of TF-5 over TF-4. basically TF-5 replaces TF-4.

TF-5 and TF-4 are designed to compliment each other. Two fixers for two customer bases based on preference, workflow or need.

PE is correct on the differences btwn 4 and 5. Also, for your pyro needs:

I wouldnt sweat it will work fine. IF uncertain buy and alkaline fix and do a 'taste' test, see if you can tell the diff btwn the two types. I use pyro-hd and cant see the difference btwn the different fixers I have.

And there's always Kodak Flexicolor Fixer, made for colour work but good and cheap for black and white (film and paper). Not alkaline, but just slightly acid.

Don't forget that fixers like Kodak Rapid fix and Ilford Rapid Fixer/Hypam (and a whole host of others) also work well with all types of Pyro developers with no loss of stain, while they are nominally acid fixers pH 5.2-5.4 isn't enough to cause problems.
