Developers with long shelf life

[p.giannakis]

I'm using Ilford Perceptol. I keep the solution in an old wine bottle of 1l. Needed is 100 cl for a film. I close the bottle with a rubber cork and suck out the oxygen with a small hand pump. These corks and pumps are available in liquor stores. The brand is Vacu-Vin.

How long will it last in the wine bottle with the air pumped out Erik?

Not forever, but I think about a year. Of course it matters how much is left in the bottle. Ten films can be developed with one liter of dissolved developer (Perceptol is a powder). You can keep the bottle in the fridge.
