Introduction

The ADOX ADOSTOP ECO 100ml is a highly effective, eco-friendly stop bath designed to halt the development process during black and white or color film processing. Crafted by ADOX, one of the most respected names in analog photography chemistry, this stop bath offers a safe, odor-free, and biodegradable solution that’s ideal for darkroom enthusiasts, students, and professionals alike.

Unlike traditional stop baths that emit a strong, unpleasant acetic acid smell, the ADOX ADOSTOP ECO 100ml uses citric acid as its active component, making it much gentler on the nose and the environment. A built-in indicator dye helps signal when the stop bath is exhausted, preventing processing errors and ensuring precise development results.

If you’ve been searching for a cleaner, safer, and more pleasant stop bath without sacrificing efficiency or reliability, the ADOX ADOSTOP ECO 100ml is your ideal choice.

 What Makes ADOX ADOSTOP ECO 100ml Different?

Traditional stop baths have long been a necessary part of darkroom film processing. Their role is simple: to immediately stop development by neutralizing the alkaline developer. However, many stop baths use acetic acid, which emits strong vinegar-like fumes, causing discomfort in poorly ventilated darkrooms.

ADOX ADOSTOP ECO 100ml solves this problem by using citric acid, a natural, odorless compound. As a result, this stop bath is non-corrosive, non-toxic, and pleasant to use, even in small, closed darkroom spaces.

The integrated indicator dye is a standout feature. During use, the solution retains a bright color (usually red or orange). Once the solution becomes neutralized by developer residue and reaches a pH above 5, the dye fades or changes color, signaling that the solution is exhausted.


 How to Use ADOX ADOSTOP ECO 100ml

The ADOX ADOSTOP ECO 100ml comes as a liquid concentrate, making it easier and quicker to prepare compared to powder-based chemicals. Here’s how to use it in your darkroom:

  • Dilution: Mix 1 part concentrate with 9 parts water (1+9 dilution)

  • Working solution yield: 100ml of concentrate makes 1 liter of working stop bath

  • Usage time: 10–30 seconds in the stop bath is typically sufficient

  • Agitation: Use standard continuous or intermittent agitation

  • Color indicator: Watch for color change to know when it’s exhausted

This product is perfect for use after any B&W film or paper developer and can be followed by a standard fixer such as FOMA Fix P U1.


 Environmentally Friendly Chemistry

The ADOX ADOSTOP ECO 100ml lives up to its name. The “ECO” in its title isn’t just a marketing term. ADOX carefully formulates this product to ensure it is:

  • Free from acetic acid

  • Biodegradable and non-toxic

  • Safe for home disposal in small quantities

  • Ideal for educational institutions and community darkrooms

This makes the ADOX ADOSTOP ECO 100ml not only safer for humans but also kinder to the planet, aligning with the growing demand for environmentally responsible darkroom practices.


 Compatible Film and Paper Types

The ADOX ADOSTOP ECO 100ml can be used with:

  • All traditional black and white films (Ilford, Kodak, Foma, Rollei, ADOX, etc.)

  • Resin-coated (RC) and fiber-based (FB) B&W photo papers

  • Color film and color paper processing (C-41 and RA-4), though it’s primarily used for B&W workflows

It pairs perfectly with:
