    Residual Hypo Tester 50ml

    The residual Hypo Tester is used to test the washing process of prints.

    For example, you would run a test page through the washing process, and drop a bit of the hypo on the print. If it liquid turns yellow, the process/print is not clear of Fixer and you qould re-wash the actual prints.

    The residual Hypo Test is a simple chemical test that can be used to determine if a print or film strip has been adequately washed. The test is based upon the formation of a yellow stain of sylver sulfide-silver thiosulfate on the white of atest print, or the clear area of a negativefilm stripwhen the test solution is applied.

    The reliability of the test depends upon the washing procedure.

    Shake well prior to each use.


    - Simple tester shows if there is residual fixer in the printer
    - If fixer is still active then simply return the print to the wash until it is all removed.
    - Ensures archival washing of fibre prints.
    - Removes all fixer particles.
