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.
Dilute the FX20 1+9 with water and fix for 2 minutes or 1+4 with water for 1 minute. When the clearing time exceeds twice that of a fresh fixer then the fixer should be discarded.
FX20 will keep in good condition for at least one year in sealed containers. Working solution will keep for several months in tightly capped bottles with the minimum of air. During use FX20 will keep in good condition for about one week in the open dish and for about two months in a deep tank with a floating lid.
