I was all set to pour the developer into the Paterson tank. I had mixed up 1 Litre of D76 working solution at 1:3 but I got interrupted. That was 48 hours ago. The developer has been sitting in a full 1 Litre bottle for 48 hours in a pretty cool room. Is it still good? I can't seem to figure it out from the Kodak (Alaris) data sheet.
If you've already diluted it 1:3, its oxidized by now. Make fresh.
Ha this is a chance to test our collective wisdom. Me personally I would mix fresh but for APUG sake I I would do a short snip test with the old AND the new, and compare.
I'm curious to find out if the OP used it (and what was the result), or discarded it.
It makes no sense to use a diluted developer that has been left out to oxidize for two days, only to find its ruined a roll of film. You're saving 25 cents worth of chemistry, but probably ruining a 9 dollar roll of film.
Well it has been sitting in a full bottle for only 2 days but you and the the others may be right that it is "shot" but isn't the above an argument for testing a leader in it first?

As long as it's not turning brown(very unlikely) it's fine.
For the sake of the OP who has received conflicting responses as to whether his 2 days diluted developer is "toast" or not, can I ask if those who believe it is "toast" have had a bad experience of using 2 day old diluted D76 in the same circumstances as the OP?
Thanks

This may well be the case, Matt but in what circumstances? Some respondents have said it will be fine with no qualifications on that statement at all, others say it may be fine but use the leader test and yet others are in the "dump it " categoryDiluted film developer is unpredictable, inconsistent, unreliable and is like a ship - when it goes down it can take the crew (the film) with it.
All I was trying to do was find out what the experiences of the "dump it " respondents were of a dilution in similar circumstances as the OP? I am convinced that there will come a point at which all categories of respondents will agree that diluted D76 has become almost certainly or certainly "dead" but is this 2 hours, 4 hours, 8 hours etc
The point being that there is not likely to be any such point, because if you don't use it promptly, "Diluted film developer is unpredictable, inconsistent, unreliable".
My answer, and a few others was "test it". So IMO an answer one way or the other is not necessary.OK, Matt, I give up. Time I did that more often
