Ilford PQ UNIVERSAL is a liquid concentrate dimezone- s/hydroquinone developer suitable for the dish/tray developing of all RC and FB black and white photographic papers. Used at a dilution of 1+9 it is clean working and has excellent keeping properties. It gives a slightly warm of neutral image tone with most papers.
Additionally, PQ UNIVERSAL can be used to dish/tray process ILFORD and some other technical films. It is also suitable for 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. For film processing applications PQ UNIVERSAL developer is designed for use at ambient room temperatures, nominally 20ºC/68ºF.
We do not recommend its use for high temperature or machine processing applications
