Fotospeed FX20 Rapid Fixer is a general purpose liquid fixer concentrate that has no hardener added and is suitable for use with a wide range of B&W photographic materials. FX20 is very long lasting and will not, as with other brands of fixer, bleach back the print's highlights where extended fixing times are desirable.
Where a hardening fixer is required then add RH100 Rapid Hardener to the fixer working solution.
Similar to Ilford Multigrade Fixer, Ilford Rapid Fixer and Ilford Hypam Fixer.
