Electron Microscopy Sciences Pq Universal Developer

Electron Microscopy Sciences Pq universal is a liquid concentrate dimezones/hydroquinone developer which is suitable for all RC and fb black and white photographic papers. It is used at a dilution of 1+9, it is clean working and it has excellent keeping properties. It gives a slightly warm neutral image tone with most papers. In addition, pq universal can be used to dish/tray process ilford as well as 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. Pq universal developer is designed for use at ambient room temperatures, normally 20 degree c/68 degree f. We do not recommend its use for high temperature or machine processing applications. - EMS
