Ilford Ilfostop Stop Bath 500ml

Ilford Ilfostop Stop Bath

Ilford Ilfostop is a low odor, citric acid-based stop bath designed to immediately halt the development process of black and white photographic films and papers. It neutralizes the developer, preventing further development and thereby protecting the image quality.

Function and Benefits

• Stops development instantly by neutralizing the developer.
• Prolongs the life of the fixer bath by preventing developer carryover.
• Contains a pH-sensitive indicator dye that changes color from yellow to purple when exhausted, signaling the need for replacement.
• Recommended for dish and tray processing of photographic paper and deep tank processing of film.

Usage Instructions

After development, films and prints should be rinsed in Ilfostop to ensure the developer is completely neutralized before fixing. If a stop bath is not used, thorough water rinsing with frequent water changes is necessary to avoid fixer contamination.

Safety Precautions

When handling and mixing Ilfostop, it is recommended to wear gloves, eye protection, and an apron or overall to ensure safety.
