I've been using Pyrocat HD occaisionally for the last 1.5 years. I've had two recent, complete and unexpected failures of it: Once with 'old-stock' but freshly opened developer from Photographer's Formulary pre-mixed kit that was slightly older than 6 month recommended storage time from receive date to opening.
The second failure was with new and freshly opened PF Pyrocat HD developer that I stored immediately in brown glass bottles. It worked fine for 2 1/2 weeks and then failed overnight. I had to toss the remainder.
PF told me to use pyrocat HD right away, store in glass as the brown plastic their required to ship in 'breathes'.
1) anyone else with similar experiences of pyrocat HD failure? What did you do to prevent it in subsequent use?
2) Also I need a source for small actinic bottles with airtight stoperred (ie, teflon, etc top. - I don't know how airtight the glass on glass of typical brown jars is, do you?
In the meantime I have gone back to Wimberly pyro (which appears much more robust) - but Pyrocat HD is so good in the Jobo I don't want to give up on it yet.
Any feedback appreciated.
