Acufine is a maximum acutance, ultra-fine grain film developer combining optimum quality, with higher than normal effective film speeds. It is a modern developer formulated for modern emulsions and is outstanding in its ability to fully exploit the inherent capabilities of any film.
Acufine’s higher speed ratings permit the use of slower films, with superior grain structure and resolution in situations that previously required high speed films. Acufine is packaged in single-mix dry powder form, readily soluble in water ( 70° to 90°F ). Although the water in most areas is suitable, we recommend the use of distilled water wherever the mineral content or alkalinity is high.
The developer may assume a slight coloration, when mixed, which in no way will affect its chemical properties.
To minimize oxidation, Acufine should be stored in full, tightly capped bottles of amber glass or polyethylene. At frequent intervals, soak overnight all storage and mixing equipment in a solution of approximately
one ounce of sodium sulfite per gallon of water, and then rinse thoroughly.
