    Depends on what it is. What does the manufacturer say?

    You could do a test roll, but if you really care about whats on the film, mix fresh each time and use it within 30 days.

    i have had sudccess in that past with using film dev thats been used a few times and then sat for about 2 months in the past (ilford chem and film). although i have had film with older devoloper come out almost hazy like it wasnt processed long enough.

    the bottom line: if you care about whats on the roll, just mix up some fresh chem for the couple bucks it will cost. letting a couple bucks in chem get in the way of a possible lost keeper is not worth it IMO

    Yep, I'd rather just use fresh chemicals rather than risk losing the roll.

    Test it if it's a lot or if you mind making more possibly unnecessarily. I have some HC110 'B' since May. Still going strong. Course I have it in a gallon brown plastic jug and when it gets low I mix two or three liters in on top of what's left. Not worried about strength as I only one shot anyway.
