Ilford Rapid Fixer is a non-hardening rapid fixer supplied as a liquid concentrate that should be diluted with water for use. It is easy and convenient to use in the range of 18°C (66°F) for fixing black and white film and paper in all manual and machine processing applications. The fixing process assures that the latent image remains on the film or paper. This step is general preceded by a stop rinse and followed by a hypo wash to remove any trace of the fixer which might cause staining and degradation of the image.

 

At a 1+4 dilution, RC papers should be fixed from 30 seconds to 1 minute. Fiber based prints should be fixed for 1-2 minutes depending on the dilution. It should be noted that Ilford recommends that gloves, eye protection, apron or overall be worn when handling and mixing all chemicals. Ilford Rapid Fixer must not be used with other fixing hardeners. The fixing agent in Ilford Rapid Fixer is ammonium thiosulphate and contains no sodium thiosulphate (hypo).

 

This fixer is good for approximately 600 135–36 films or 2000 20.3 x 25.4cm (8 x 10″) RC prints or 1000 20.3 x 25.4cm (8 x 10″) FB prints.
