Life of separate C41 Chemicals

[martin s]

I use the Fuji C41 Press kit, it consists of a separate bleach and fix. The 5L version includes 5L dev, 5L bleach, 5L fix and 5L stabilizert (20L of chemicals, all in all).

I can order all those chemicals separately (I just found out), now the question is: how long does each chemical last?

The developer is exhausted at some point, no question. It's probably the first chemical to stop working, so I'll order that separately. Now what about bleach? Does anyone have experience with that? The fixer I'm guessing will last a lot longer than both dev. and bleach, and so does the stabilizer.

As an example: I divided the 5L Kit in 5x1L kits, and while I'm through 4L of developer already I still have my first batch of 1L fixer and 1L stabilizer (they both still work, as far as I can tell).

Hi Martin;

I don't know the answer to your question. But, I can tell you that oxidation is the cause of early expiration. Store the chemistry in dark-plastic bottles. Squeeze the bottle until the liquid comes to the top and cap the bottle with as little air trapped in the bottle as possible. If you're dividing up the chemistry this could be harder to do. Store the chemistry in a cool dark environment. p.

This is not an issue, I go through a lot of chemistry very quickly. I used 4 liters of the Fuji Kit within a month, I usually have a large backlog.
