Adox RA-4 Kit to Mix 2500ml Chemical Kit

Adox RA-4 Kit to Mix 2500ml Chemical Kit

Innovative color development kit with only one part per bath. All you have to do is dilute the developer and bleach 1+4 each and you're good to go. This developer and bleach-fix kit contains everything you need to process color papers in the RA4 compatible process. The contents are enough to process approx. 54 square feet of paper or approx. 115 sheets of 18x24 cm (7 in x 9.5 in).

Of course, you don't always have to prepare 2.5 liters at a time. Processing should take place at 95 degrees Fahrenheit. The development and fix time is then 45 seconds each. After approximately 22 square feet of paper have been processed per liter of batch, the bath should be disposed of and new chemicals should be prepared. If the process continues longer, the color shifts, blue blackness (exhausted developer) or occupied lights (exhausted bleach-fix bath) will eventually occur. 

The rinsing temperature should not be below 86 degrees Fahrenheit or if not, a stabilizing bath should be used, otherwise the reddish color of the bath may not be completely washed out and the images may have a red cast. It is therefore important to only use well-watered sample strips to assess color filtering.
