Here is the way I use it.....

For a 1 Liter mix:
924 mL water
60mL Part A
8mL Part B
8mL Part C

Develop 2:30 At 98dF Then dump it as one-shot. It is not worth saving or taking chances. This chemistry has excellent shelf life. The active component is Part C and could be kept in the frige is desired. I use the 5 gallon minilab kits and decanter the Part C into 100mL glass bottles and keep them in the frige 'till needed.
