  • Why is the fixing agent used?

    Its purpose is to remove or clear all unexposed and undeveloped silver halide crystals from the film emulsion allowing light to pass through the film image and permitting viewing of the radiographic image on a view box.



  • What is the agent used for fixing dyes?

    Formaldehyde is used in the textile industry for dyeing, as dye fixing agents and for achieving flame retardance properties.



  • What is the most popular fixing agent?

    Formaldehyde (10% neutral buffered formalin) is by far the most popular fixative used in histology since it penetrates the tissue well and creates crosslinks without affecting the sample tissue's antigenicity. While it is relatively slow to fix, it is highly recommended for immunohistochemical techniques.



  • What are the ingredients of fixing agent?

    fixing agent: sodium/ammonium thiosulfate, dissolves unexposed silver.

    hardener: potassium alum, to harden the gelatin emulsion in film.

    acidifier: sulfuric/acetic acid, to remove any residual alkalinity from previous developing.
