Mixing Prescysol EF Working Solution

Marco S. · Feb 19, 2006

In reading PF's instructions regarding mixing the concentrates it states this:

This kit contains two bottles of stock solution - one marked "Solution A" and one marked "Solution B". To make the standard working solution mix the stock solution and water in the ratio of 1:1:100.

For example: to make 500 ml of working solution:
add 5 ml of Solution A
add 5 ml of Solution B
add 500 ml of water at 74° F/24° C.

If you follow these instructions to make 500ml (which I would need for a Jobo 1520 tank) you would end up with 510 ml of working solution, not 500 ml. So should the instructions read "to make 510 ml of working solution...?" I want to make sure I am mixing this properly.

The working strenghth solution would be 510ml of developer. I use A.P tanks that are 600ml tanks so my working strength solution is 612ml.

Just follow the rest of the instructions to the word and you will be well happy with the results.

the dilution is 1 to 1 to 100. so 510 ml of working solution is correct

Thank you...

I can't wait to try it with FP4+, Acros 100 and Delta 100 . I picked up some TF-4 fixer as well. This will be my first experience with a staining developer. I'm excited!

I can't imagine you will use anything else once you have used it. It makes life that little bit easier. And you will be using one development routine, so you are less likely to make mistakes.

Good Luck
