Why Choose Ilford Ilfostop Stop Bath 500ml?

How Ilford Ilfostop Stop Bath 500ml Works

During black and white film development, timing and temperature are crucial. Once the film has been developed, it must be immediately immersed in a stop bath to halt the chemical reaction. The Ilford Ilfostop Stop Bath  does this by neutralizing the alkaline developer with a mildly acidic solution. This prevents overdevelopment and ensures that subsequent fixing works efficiently.

Mixing and Usage Instructions

The Ilford Ilfostop Stop Bath 500ml is a concentrate and must be diluted before use. The recommended dilution is 1 part Ilfostop to 19 parts water, making 10 liters of working solution from one 500ml bottle. This is perfect for multiple rolls of film or several sessions of print development.

To use:

1. Dilute the concentrate in clean water.

2. After development, immerse your film or paper in Ilford Ilfostop Stop Bath  solution for 10–30 seconds.

3. Proceed to the fixing stage.

Always refer to the official Ilford datasheet for precise guidance.
