    Hi danyc,

    According to Kodak the limit is about 25 rolls (actually, that's for a quart but it's close enough), however I use a hypo-check test solution.

    It is not a "rapid" fixer.

    Are you sure about that? Any off the shelf fixer which is
    a liquid concentrate is a rapid fixer. Dan

    Danzyc,I learned a handy technique a few years ago from a long standing member.It's called a "clip test".Simply snip off about 2 inches of film before you load it onto the reel.This includes the leader.
    Fix until clear then double the time for your film.This test is to make sure your fixer is still active.

    Dear Dan and danzyc,

    My sincerest apologies. It took me longer than it should have to track down the MSDS for Polymax T fixer and it seems that it is an ammonium thiosulfate fixer.

    I don't use T-max film but by all accounts it is slow to fix.
    That is due to it's having some silver iodide as part of the
    emulsion's silver halides. The iodide is extremely insoluble
    so takes more time and more fixer.

    Give or take some little you can fix twice as much film and
    in half the time using other than iodized films.

    BTW, is Acros an iodized film? Anybody? Dan

    There is no such product listed as T-Max Fixer at Kodak's US web site. This is the closest they've got and it jives with the naming conventions used for the Polymax/TMax product lines.

    You weren't so far off in stating the fixer to be not
    a rapid fixer although the ammonium makes it so.

    With the film mentioned even rapid fixers are slow.
    I've never tested but believe the old slow sodium
    fixer may be quicker than the rapid when it
    comes to iodized emulsions. Dan
