ilford rapid fixer alike fixer recipe?

I was wondering If anyone know something like commercial fixer recipe.
You know, when you buy a liter of ilford rapid, you dilute it and get total of 4 liters.
All the recipes I have makes 1 liters and If I add more chemicals , I don't think I will be able to dissolve them all.

thanks

All rapid fixers are of pretty much the same composition. You can buy ammonium thiosulfate as a liquid solution IIRC 60%. The solid is not very stable and hard to obtain. Whether you bought Ilford, another brand or just ammonium thiosulfate you are paying a lot to ship water. In the end you are not going to same any significant amount of money mixing your own.

Oh thanks for the info. It isn't much about the money, I'm just wondering what does their formula look like.
If somebody have a copy, please add it here.

The sodium salt is a more practical fixer to scratch mix.

(there was a url link here which no longer exists)

Typical formulas include Ammonium Thiosulfate, some form of Sulfite (e.g. Sodium Sulfite plus Sodium Metabisulfite) to both protect the Thiosulfate from oxidation and to establish fixer pH. Additionally there could be some sequestering agents for water hardness, although they may not be necessary at lower pH. Based on e.g. (there was a url link here which no longer exists), it should be fairly easy to construct concentrated formulas from these components.
