bippi, I'm not sure I understand your question. But...ID-11, "officially," will last 6 months in a full container as stock (you always store as stock, never diluted, of course), and I've had it last closer to 9 months in 2/3 full ones (so quite a bit of air) without a problem. D76/ID-11 is a pretty durable formula.

I'm not there
I have a tiny bit of d76 left. Its nice and red, looks like cherry juice. I have no idea why im still keeping it, or why I made this post.

Kaiyen no wonder why you could´t understand me, I quoted an old post from the thread which made no sense what so ever to the question I was trying to make
, sorry for the misunderstanding. But you answered my question. So ID-11 should work for me.

Indeed, Xtol is also based on Ascorbic Acid and in combination with some other ingredients the Xtol is very sensitive for metall ions in your water. So depending on your (tap) water the lifetime of Xtol can be very different. Normally 4-6 months. The developer is known about this "sudden death Xtol" syndrome. Indeed no change of color and suddenly it will not work anymore.
One of the reasons to make Xtol with demi-water and put an expiration date on it and simply dump it after those 6 months.
Indeed only available in 5 ltr. packing.
D76/ID11 (same receipture) has a lifetime of 6-8 months. Depending on your developing tank you can divide a stock in "handy" one shot usable parts: 125ml or 250 ml bottles, for using 1+1 (Silar, H.D. polyetylene, PET or glass (=no diffusion at all). With almost no space left in the bottle, almost no oxydation possible. With full glass bottles you have to be carefull: They can crack when the temperature is going down (Iceland ).
UV light (radicals) and high temperatures will also shorten the lifetime of developers. In general the best overall temperature to store them: 10-12 degrees C and in the dark (or brown/black bottle). Some developers will form crystals under 4-8 degrees C which are not going into the solution till it's over 45-50 degrees C, not very practical to store them at fridge temperature.
D76/ID11 is a general all purpose, semi-compensating developer.
A general liquid version we are selling is AM74/Rollei High Speed. A fine grain semi-compensating liquid developer partial based on hydroquinon (<1%), pH around 10,1. You can use it from 1+7 (Stock) and 1+9 to 1+19 as one shot developer. Very light yellow to light brown, it will work. Brown to dark brown: Dump it which will be the case after 8-10 months. Very predictable and easy in handling. As 1+7 till 1+9 it's a depth developer, up from 1+15 - 1+19 it works in the film surface.
AM74 is also suitable for rotary development and very sucessfull for a wide range of B&W films. (Including Rollei R3, Rollei Retro films (=APX100/400) ).
It's standard packed in Silar (H.D. plastic) bottles and a product from Amaloco Photochemicals, the Netherlands.
