Kodak Rapid Fixer storage life.
I was wondering about buying a cubitainer of part A of Kodak Rapid Fixer
instead of mixing F-9 fixer all the time. But sometimes I do not use it very fast, so perhaps I should get the smaller size. How long does the stuff last, unmixed, in the cubitainer? I have great difficulty finding this information on Kodak's web site. They tell me the lifetime of working solutions in an old J-1, but that is not available anymore, and it does not tell me what I want to know. -- .~.

Kodak Rapid Fixer storage life.
FWIW: I use Arista rapid fixer and a 1 gallon jug lasts about
1 1/2 years before the (now) mostly empty jug starts to throw yellow sulfur. It might last longer in the 'fridge, but I have never tried keeping it there. TTBOMK, most all modern "Rapid" fixers are ~60% ammonium thiosulfate with a pixie dust of hardeners and acidifiers/buffers. At the time I investigated Arista was the cheapest fixer available. I don't think there is any advantage to spending extra money for boutique fixer. -- Nicholas O.

I don't think there is any advantage to spending extra money for boutique fixer. Years ago I had a darkroom in the garage (an outbuilding) that was only heated when I wanted to use it. The fixer settled out in a sort of 'angel hair' formation. Although this was probably the garden variety Kodak mix from a powder variety. I stand ready to be chastised for this comment! In recent years, I've gone to B&W chems that come in concentrate form and can be mixed as needed. |
