Ilford Ilfostop Stop Bath 500 Milliliter Bottle 0.5 Liter
MFR#: 1893870. Low odor, liquid concentrate, citric acid stop bath for film and darkroom paper use. Paper and film stop bath solution. Economical liquid concentrate. Dish/tray paper or deep tank film processing. Prolongs fixer life
This is a Ilford Ilfostop, a low odor acid stop bath.
Normally, when development is completed, films and papers are subjected to a
stop bath rinse. This immediately halts the developing process by neutralizing
the developer.
ILFOSTOP contains an indicator dye that is pH sensitive and
changes color from yellow to purple as the stop bath becomes exhausted. It is
specifically recommended for dish/tray processing of paper or deep tank
processing of film. ILFOSTOP helps to maintain the activity and prolong the
life of the fixer solution by reducing carry over of excess developer
(alkaline) into the fixer bath (acidic). It is not recommended for machine
processing applications as the short fix and wash times often used may leave a
residual dye stain on films and prints. The longer wash times usually
associated with dish/tray and tank processing minimize this risk.
