Plain Hypo is the optimum second fixing bath. Most unexposed silver halide is removed by the first fixing bath, and the second bath finishes the job. Also recommended as a second fixing bath prior to toning. The pH of a mixed Plain Hypo solution is slightly above neutral pH (not acid), so if used in combination with Alkaline pH fixers, all the fixer washes out easily. Since it is used at nowhere near its capacity, this solution can be reused and lasts a long time. Testing procedure for re-use is included. Sold in 4 package sets. Each package makes 2 liters.

Photographer's Formulary Plain Hypo is well packaged, easy to mix and works very well as a 2nd fixing bath. It is without a hardener, and I find plain hypo the best to use as a final step before toning.
Each package makes for 2 liters of solution, and I had a mild sense of panic regarding the storage of 4 liters of hypo in a standard gallon storage jug. Not to worry, it simply reduces a little air space in the jug and fits just fine!
Really glad Photographer's Formulary continues to supply this product.
