Typically dilutes 1:9 to make 10L working solution.
Ilford PQ universal is a liquid concentrate developer suitable for the dish/tray developing of all RC and FB black and white photographic papers where it delivers a very slightly warmer tone to Ilford Multigrade. We classify it as a neutral-warm tone developer.
In addition PQ UNIVERSAL can be used for processing some technical films and also the dish/tray developing of general purpose sheet films when a fast working, high contrast developer is needed and a high degree of enlargement is not required.
