XTOL keeps how long after mixing?

Hey all,

Pursuant to warm reviews from people all around, I'm trying out xtol for some rolls. I hear they have the defects fixed and everybody's happy now...

I use a small amount of chemistry at any given time - usually I develop one roll at a time 'cause I'm not usually shooting a lot of the same film concurrently. The smallest batch of xtol one can mix is a liter -- OK, no problem. Use 250 mL for processing, and then the other 750 mL... Gets stored in airtight plastic chemistry bottles? (They're specifically for photography, got 'em at B&H).

But how long does it hold once mixed? I've read the page at kodak's website but I've heard that the party line is a load of bull.

1. Used developer: how long can it hold once mixed? (I'm not into replenishing).

2. Unused Developer: ditto.

Thanks,

Idan
