How do I check to see if my fixer is exhausted if I can’t use “Hypo-Check?”

Edwal makes fine products, but Hypo-Check indicates premature exhaustion with Sprint™ RECORD Speed Fixer. Instead, try our fixer test. Put a piece of undeveloped film in a small beaker of fixer working solution (1:9) and stir. If the film’s emulsion does not clear, that indicates the fixer has worked to capacity, and will no longer be effective in removing silver from the film. A new batch of fixer working solution should be made.
