Rollei RXN Fix Neutral is a pH neutral rapid fixer for processing black and white films and photographic papers. However, RXN Fix Neutral is specially designed to make fibre-based papers suitable for archiving. The working solution is virtually odorless. RXN Fix Neutral is a non-hardening fixer. This universal fixer is suitable for tray, tank and machine processing (up to 26°C). Dilution 1 + 4, 1 + 7 and 1 + 9..It ofers acid-free fixing with reduced fixing and washing times plus improved archival stability. Extremely low acidic content means it will not harm the paper base.
The standard dilution is 1+9 and fixing will last 2-3 minutes. A higher concentration of 1+4 will reduce fixing to one minute. Being odourless, it makes for a more pleasant working environment in your darkroom. It also has a pH neutral balance. We recommend it for use in the Rollei Black Magic photo emulsion system. The use of stop bath is recommended to extend the life of the fixer.
