Ilford PQ Universal Developer
ILFORD PQ UNIVERSAL is a liquid concentrate developer suitable for the dish/tray developing of all RC and FB black & white photographic papers.
With excellent keeping properties, PQ UNIVERSAL gives a slightly warm image tone with most black & white darkroom papers. Supplied as a concentrate, it is typically used at a dilution of 1+9.
When a fast working, high contrast developer is needed and a high degree of enlargement is not required, PQ UNIVERSAL can also be used to dish/tray process technical films such as ILFORD ORTHO COPY PLUS as well as some photographic sheet films (see the tech data sheet).
For development times and developer capacities, please refer to the technical data sheet.
