    When should I use new fixer?

    How long time a fixer dilution last for?
    Or, how many times should I use a dilution of fixer?

    Are you asking about prints? I find Thomas' reply in this thread to be a spot on! I printed it out and use it as a reference.

    Does this help?

    Thomas's reply was great (as usual). But, what about film?

    for film, you should us a separate fixer bath/s than prints
    do a clip test.... take an processed piece of your favorite film
    and see how long it takes to clear ( room lights on ) in your freshly mixed fix.
    fix your film for 2x that time ( half 1 bath half 2nd bath ) ... when your clear time
    becomes 2x the original # your first bath is spent, mix new, and number 2 becomes #1
    so your fresh bath is #2 ...

    have fun

    What I do for film is keep track of how many rolls I've run through the fixer. Then I discard it when it has reached half the manufacturers recommended capacity. For Iford Hypam which I use, this is 12 rolls per liter.

    does anyone do a two bath fix on film? I could certainly see it for open tanks (dip and dunk) or for tray processing.

    In fact, I'm wondering if moving to Thomas' method (which seems to be Ilford's recommendation for print developing) for all of my rapid fixer need would be the most reasonable option. As it is, I seem to err on the side of under-using fixer rather than approach exhaustion limits.

    By the way, there are fixer test kits on the market, and if exhaustion is a concern you can certainly check your fixer strength before using it. You also want to filter (with filter paper) the fixer before putting it back into the bottle and before using it. Nobody is happy with silver deposits on film.

    i use 2 baths for everything.

    the problem with the fixer test kits is sometimes
    they are made for a specific fixer, and will give you a false reading.
    i use sprint speed fixer and when i use edwals hypo check it gives me a
    indication my fixer is exhausted when it isn't ...

    the point of the 2 fixer baths is that the 1st one does all the work, and the 2nd one does "sloppy seconds"
    and if you use 2 baths, even if your first one is close to dead, #2 will completely fix the film or prints ..

    YMMV

    have fun!

    I didn't know that there is a number of times recommended from the company to use their fixers.

    I didn't find this information on the bottle...

    What fixer are you using?

    If it is Kodak Fix, the capacity information is shown on this table (along with a whole bunch of other good info).

    If it is Ilford Rapid Fixer, the capacity information is shown on page 2 of this information document (24 rolls per litre of working solution at film strength).

    I think it is a general rule of thumb that nowadays, the best source for a lot of technical information is the manufacturer's website.
