Kevin, I haven't used Mytol but I have used Pat Gainer's PC-TEA. PC-TEA produces results that are fully comparable to Xtol and has the advantage of a very long shelf life.Originally Posted by kjsphoto
FYI, Xtol, Mytol and PC-TEA are all Phenidone - Ascorbic Acid (or Ascorbate) developers. They all produce excellent and similar results. The PC-TEA Stock Solution does not contain sulfite or water. Xtol and Mytol stock solutions do contain sulfite and water.
Expected shelf life for the stock solutions.
Xtol: About 6 months, for Stock Solution stored in glass bottles.
Mytol: About 6 months, for Stock Solution stored in glass bottles.
PC-TEA: Expected to have longest shelf life - by far. My PC-TEA stock solution has now passed 4 months with no activity change seen in 1 liter of stock solution stored in a Nalgene bottle.
