How to Use ADOX ADOSTOP ECO P Stopbath with Indicator 1000ml

FAQ – ADOX ADOSTOP ECO P Stopbath with Indicator 1000ml

This stop bath uses citric acid instead of harsh acetic acid. It contains no toxic fumes, no corrosive agents, and no hazardous chemicals, making it biodegradable and safe for schools and home darkrooms.

2. How does the color indicator work?

The working solution starts yellow. Once the stop bath becomes exhausted, the indicator turns purple/red. This visual change ensures you always replace the solution at the correct time, preventing processing errors.

3. What is the correct dilution for this stop bath?

ADOX ADOSTOP ECO P Stopbath with Indicator is mixed at:
1+19 (50 ml concentrate + 950 ml water = 1L working solution).
This dilution works for both film and paper processing.

4. Is this stop bath safe to use in enclosed or poorly ventilated darkrooms?

Yes. Since it is odorless and fume-free, it is ideal for:

• Home labs
• School darkrooms
• Community workshops
• Spaces with minimal ventilation
  It does not produce the strong vinegar smell associated with acetic acid stop baths.

5. How long should film or paper stay in the stop bath?

• B&W paper: 10–30 seconds
• B&W film: 30–60 seconds
  The mild citric acid instantly halts development, preventing overdevelopment and keeping your fixer clean.

6. What is the shelf life of ADOX ADOSTOP ECO P concentrate?

If stored tightly sealed and away from heat, the concentrate lasts up to 2 years. The working solution should be monitored using the color indicator and replaced immediately when exhausted.

7. Can this stop bath be used with any B&W film or paper brand?

Yes. It’s compatible with all major brands, including:

• Ilford
• Foma
• ADOX
• Kentmere
• ORWO
  Since it’s a universal citric acid stop, it works with all B&W developers and fixers.

8. Why should I use a stop bath instead of water?

A stop bath:
✔ Instantly halts development
✔ Prevents uneven or overdeveloped results
✔ Significantly extends the life of your fixer
✔ Improves overall process consistency
Using only water does not neutralize developer efficiently, especially during long printing or film development sessions.
