Kodak 1 Gallons Rapid Fixer Solutions A and B for Black and White Film

The Kodak 1 Gallon Rapid Fixer Solutions A and B kit is a liquid black-and-white film processing chemistry set designed to prepare 1 gallon of working-strength fixer. Kodak Rapid Fixer has long been a trusted option in traditional darkrooms because it offers fast, efficient fixing performance and practical handling for photographers who process black-and-white film regularly. Whether you are developing 35mm, medium format, or sheet film, this fixer is intended to help remove unexposed silver halides thoroughly so negatives can be washed, dried, and archived properly.

This two-part formula is especially useful for photographers who want the convenience of liquid concentrates rather than powder chemistry. Solution A and Solution B are mixed with water to create the final working solution, giving users a dependable fixer suitable for film-processing workflows in home darkrooms, educational labs, and professional black-and-white processing environments.

Fixer is one of the essential final chemical stages in black-and-white processing. After development and stop bath, the fixer removes remaining light-sensitive silver salts from the film emulsion. This step stabilizes the negative so it can be safely exposed to light without further darkening or degradation. Kodak Rapid Fixer is formulated to work quickly and efficiently, helping photographers maintain a smooth, repeatable processing routine.

• Two-part liquid fixer concentrate
• Designed for black-and-white film processing
• Mixes to make 1 gallon of working solution
• Rapid fixer formula for efficient darkroom use
• Well suited for home, school, and lab darkrooms
• Convenient liquid chemistry format compared with powder-based alternatives

For film shooters who process regularly, a rapid fixer can streamline the workflow while still supporting high-quality results. Liquid concentrates are typically easier to measure and mix than powder chemistry, making setup simpler and reducing preparation time. Kodak Rapid Fixer is also a practical choice for photographers who want a known, established chemistry option from a brand with deep roots in photographic processing.

Because it is intended specifically for black-and-white film, this kit fits naturally into a traditional monochrome processing workflow. It can be especially valuable for photographers developing multiple rolls at a time, classroom instructors teaching analog techniques, or darkroom users seeking consistent results from a recognizable chemistry system.

In a standard black-and-white film process, Kodak Rapid Fixer is used after the developer and stop bath stages. Once the film has been fixed for the proper time, it is washed thoroughly and then treated according to the photographer's preferred final rinse and drying routine. Accurate timing, correct dilution, and proper agitation are essential for best performance, and users should always follow Kodak's official instructions for mixing, use, capacity, and disposal.

One of the major attractions of this product is its liquid format. Compared with powder chemistry, liquid solutions can be more convenient for photographers who want faster prep and easier measurement. This can be especially helpful in smaller darkrooms, shared educational workspaces, or mobile setups where minimizing mess and preparation time matters. The two-bottle design keeps the components separate until mixing, helping maintain stability prior to use.

• Processing black-and-white roll film at home
• Developing medium format negatives in a tank system
• Darkroom instruction in schools and workshops
• Maintaining a repeatable chemistry workflow in a film lab
• Keeping a dependable rapid fixer on hand for frequent processing sessions

• Always mix according to Kodak's official dilution instructions
• Use clean graduates, storage bottles, and processing tanks to avoid contamination
• Label mixed chemistry clearly with date and dilution
• Track film capacity and replace fixer when exhaustion is reached
• Wash film thoroughly after fixing for long-term negative stability
• Store concentrates and mixed solutions as recommended by the manufacturer

To get the most from this fixer, photographers often pair it with a complete black-and-white processing setup. Useful accessories may include a developing tank and reels, graduated cylinders, chemical storage bottles, a stirring paddle, a thermometer, a timer, film clips for drying, and a wetting agent for the final rinse. A dedicated stop bath and black-and-white film developer are also natural companions in a complete workflow.

Kodak has been one of the most influential names in photographic chemistry and imaging for generations. From film emulsions to developers, fixers, and papers, Kodak products have shaped both amateur and professional darkroom practices around the world. Rapid fixer solutions like this continue that tradition by supporting photographers who value analog image-making and dependable processing chemistry.

If you are building or maintaining a black-and-white darkroom workflow, the Kodak 1 Gallon Rapid Fixer Solutions A and B kit offers a practical combination of brand heritage, liquid-concentrate convenience, and processing utility. It is a solid choice for photographers who want an established fixer formula for monochrome film, with enough volume to support repeated processing sessions while keeping preparation straightforward.
