    My recommendation is Tetenal Dokumol decanted into smaller glass bottles (as others have recommended). It is a very long lasting developer and also a very hard working developer. Try it at 1 + 6 for 3 minutes and you will be amazed.

    Best,

    Moersch ECO 4812 is my choice. Lasts a startlingly long time as a working solution in a bottle. I bottled up my first batch in a 1 gallon plastic water jug at the end of my printing session and 3 months later it was fine. I regularly use it several days before discarding. The concentrate lasts ages, with a little Bloxygen in the bottle I'd guess five years.

    It is almost identical to Dektol in all regards.

Probably Canadian Azo and Kentmere Bromide. The result was a somewhat cold toned print. I didn't continue because it was not very economical. I think there's also a thread about using Gainer's PC-TEA as a paper developer.

    Rodinal was once very commonly used as a print developer as well as for films, as was Kodak's equivalent Kodinol (not made or sold in the US). However I think 2:25 (1:12.5) is more like what's needed with modern Rodinal to get the contrast and a good Dmax.

    Mees worked on p-Aminophenol developers himself at Wratten & Wainwright before joining Kodak, that work continued at Kodak Ltd's Harrow Research facility (which was effcetively the same Wratten team minus those who founded the Rochester facility) resulting in Kodelon, Ilford's version Certinal was released around 1908.

    Freeze it.

    I wouldn't expect any used, working dilution developer to last very long after some use. It's not just the oxygen that may be in the bottle.

    Freeze it.

    (You'll also get very cold tones.........)

    hey ron

    aged / dilute it gets better, in stock it stays normal ...
    when it ages and turns black ( after it has been dilute and had prints run through it ) it is perfect for film and or paper negatives
    sorry for my confused post !

    K.I.S.S Freeze it.

    Take any developer or photo chemical you like that degrades whilst on the shelf and just freeze it.

    There seem to be very few of us in the photo-universe that have grasped this super-simple solution, no pun intended. It works.

    LPD is essentially a phenidone (instead of Metol) based developer that is otherwise essentially Dektol. Ilford was a big proponent of phenidone back when, and had a number of formulas that were Metol replacements. I took a cursory look in my papers and couldn't quickly find the Ilford "LPD", but if someone wants it, I'll look further. Like LPD, I found it almost inexhaustible.

    Massive brain awakening. I think it's ID-67:

    PHENIDONE-HYDROQUINONE DEVELOPER, Ilford ID-67
    For Films and Plates

    STOCK SOLUTION
    Warm Water (l25 F or 52 C) - 750.0 ml
    Sodium Sulfite (anhydrous) - 75.0 grams
    Hydroquinone - 8.0 grams
    Sodium Carbonate (desiccated) - 37.5 grams
    Phenidone - 0.25 grams
    Potassium Bromide - 2.0 grams
    Benzotriazole - 0.15 grams
    Add cold water to make - 1.0 liter

    I am not sure if this is typical or not, but just before Christmas, I used up my last bit of Bromphen Stock solution. It had been sitting in my cupboard in PET bottles for around 18 months and seemed to work OK.

    Paul, Phenidone is known to be unstable in alkaline environment so your ID-67 formula would be quite unsuitable for long shelf life. Replace the Phenidone with twice the amount of Dimezone S if you want longer shelf life.
    Trying to be the best of whatever I am, even if what I am is no good.
