ILFORD RAPID FIXER is the best selling fixer for black and white film or paper processing. Rapid Fixer is very easy to mix, with a recommended dilution of 1:4 for film or 1:9 for paper. May be used in small tanks, rotary, or machine processing. Typically, a 1L bottle of concentrate will fix approximately 120 rolls of 35mm-36 film, depending on working practices (many photographers err on the side of caution and discard fixer sooner than necessary). Or, 200 8×10″ sheets of FB paper / 400 sheets 8×10″ RC paper.
Ilford Rapid Fixer must not be used with fix hardeners. See technical data sheet for mixing instructions and fixing times.
