Kodak F24 Fixer
Does anyone know the shelf life of home made Kodak F24 Fixer?
Also what area of paper a litre would fix? Thank you in advance. Cheers.

What's the ingredients of this stuff Nat? I tried to Google it but all I got was F24 fixer which is seems to be the trad sodium thiosulphate fixer with citric acid.
Thanks Mike |

F-24 has a shelf life of around 3 months according to Kodak, it doesn't contain Citric acid and the formula is correct in the Darkroom Cookbook. 3rd & 4th editions. However Steve Anchell does suggest you can add Citric Acid instead of the Metabisulphite.
In practice it will probably last over a year. Ian |

That's the stuff Mike.
Greg Davis has this on his youtube channel. https://www.youtube.com/watch?v=vRiZDbbcoDo 3 mins. 30 sec. into the video he gives the name and ingredients. Kodak F24 Fixer, sodium thiosulphate 240g sodium sulphite 10g either citric acid 22g or sodium bisulphite 25g What I am looking for is a cheap, long shelf life, paper developer. Cheers. the latter is a bit smelly apparently.

Ian you have just thrown a spanner in the works.
A bit different from the ingredients given by Greg Davis in his video. I can view The Darkroom Cook Book on the web so I will go with their information. I forgot all about the book. Cheers Mike and Ian.

It won't keep as well with Citric acid, with Metabisulphite it's not that bad, it's a standard fixer. Moulds and bacteria can grow in dilute Citric acid, Metabisulphite has strong anti-bacterial and anti-mould properties even in a weak solution.
