swamiji Posted July 26, 2012 Share #1 Posted July 26, 2012 Advertisement (gone after registration) Well I discovered that I had a bottle of zonal pro ec rapid fixer, in my cabinet, and wanted to find out how many times I can reuse before tossing it. But in my search I found out that the company that produces it is out of business. Argh. Well the bottle I have is not very old, so I might as well use it. So is there anything different about Zonal pro, than most fixers? I am used to Kodak rapid fixer, and just ran out. I guess the most important question is how many times can I reuse it? For most film it says 1:6, which is ok, and 3 minutes time which is fine, but it says little else. Oh, I am not working with a hardener, so that is not an issue.

miha Posted July 26, 2012 Share #2 Posted July 26, 2012 As a general rule, you can easily fix ten rolls of film in one litre of working strength (1+4) rapid fixer by reusing it. At least this is how I do it. Link to post Share on other sites More sharing options...
appleman Posted July 26, 2012 Share #3 Posted July 26, 2012 You could mix it with a tonic with ice and lemon. Link to post Share on other sites More sharing options...

miha Posted July 26, 2012 Share #6 Posted July 26, 2012 Is there any indicator with Zonal Fixer? No, fixer has no indicator and Zonal Pro shouldn't be different to any other ammonium based (=rapid) fixer. When in doubt make a simple test called 'Film clearing time' (see page 5): http://www.ilfordphoto.com/Webfiles/201142795282272.pdf Good luck! Link to post Share on other sites More sharing options...

fotohuis Posted July 26, 2012 Share #8 Posted July 26, 2012 You can test the condition of your fixer, amount of saturation of Silver (Ag+) ions, with a 10% KI (Potassium Iodide) solution: 10ml fixer on test + 5 drops 10% KI: When the fixer clears it has not reached the limit of 2g/ltr. Ag+. When the fixer turns on milky you have reached the limit of your fixer for films and PE/RC papers. For fiber/baryta papers the archival limit should be 1 g/ltr. Ag+. You have also Tetenal fixer test strips for this, in fact coming from the Machery-Nagel company. They have also a good pH test strips for stop bath and checking the developer buffering system. For most Citric Acid type stop bath an indicator has been build in. pH<5,5 Yellow. When your stop bath is going over pH 5,5 it's turning to a Blue color.
