Ole's Quick fix (OF-1)

[rongui]

Found this formula in my archives recently and hope it can help someone looking for the formula.

Here's one version of my akaline buffered "rapidized" fix - quantities are not critical. I use cups, spoons and dashes...

The metaborate can be used for anything, the bicarbonate version should not be used with acid stop or other acidic bath in the process (gas bubbles should be avoided!)

Mixed correctly(ish), the effect is almost as good as TF-4, and the ammonia odor is far less noticable. If it stinks too much, use less alkali next time. It can be almost odorless...

600 ml water
220g Sodium thiosulfate pentahydrate
30 g Sodium sulfite anhydrous
40 g ammonium chloride
20 cl Sodium metaborate 10% solution
OR 5 g Sodium bicarbonate

Water to 1 liter.

Interesting. Thank you.

That is similar to Agfa 304 fixer. I have used Agfa 304 in the past and it does work.

Why suffer with the pungent odour of Ammonia when you can make a neutral fixer as detailed here?

I have used homemade OF-1 fixer a couple of times, but switched to making my own TF-2 fixer. TF-2 is all I've used now for the past 8 to 10yrs.. Simple to make and very cost friendly too. Still, there is nothing wrong with OF-1 either.
