    Difference between Ilford Rapid Fixer and Hypam Rapid Fixer

    What is the difference between Ilford Rapid Fixer and Ilford Hypam Rapid Fixer?
    I normally use Ilford Rapid Fixer CAT 198 4583 to fix B&W T Max sheet film after Rollo Pyro development or Kodak Polymax VC fiber paper after development. Some how I mistakenly received 5 litres of Ilford Hypam Rapid Fixer CAT 175 8285 in my last supply order. I haven’t found any difference in reading the instructions. Is okay to make this substitution for my needs or should I send this back?

    Thanks for your help.

    they are both the same. One, the Rapid fixer was the name in the US, the other was the UK name, about a year or so ago, they moved to production plant to the UK and just kept the one name.

    There is a small difference in chemical composition, but both are used in the same way. I also think you can add a hardener to the Hypam which you can't do to the other.

    From what I've read, this is absolutely correct. I got one of those 5-liter bottles of it for Christmas so I read up on it. I do not use a hardener, but the ability to add one seems to be the only difference.

    i have not read the label, just got the information directly from the Ilford folks so didn't pay much attention. I never use hardner in this fixer so it has not been an issue.

    I got confused about that a while back too.
    I contacted Ilford, they told me that basically they were the same thing.
    The hardener thing rings a bell, but I never use hardener
