Kodak Flexicolor Developer Replenisher 20L

Hey guys! So, after waiting a couple of weeks, Kodak has finally replied to my e-mail about their 20 liter Flexicolor film developer. I am sure that many of you have used CIS-49 (5gal) for the volumes of concentrations needed to make a liter of developer, and, if you have used the 20L developer replenisher (CAT 366 7805) with these volumes, you know that there is a good bit of parts "B" & "C" left over when you run out of part "A". Also, if you have used this developer, you will find that there are no measurements on the concentrate bottles which makes it impossible to measure out the right amount of chemistry. I have a solution for you!

CIS-49 calls for:
750mL Water
75mL part A
12.5mL part B
11.73mL part C
Water to make 1L

Kodak's solution/correction to this calls for:
750mL Water
75.2mL part A
25mL part B
37.84mL part C
Water to make 1L

I hope this fixes any issues you guys may have. I know it surely fixes my problems about all the leftover chemistry (aka "wasted money") I have left over. I know I can find good use for it, but when you develop color, you want it done right.

To clear up any misunderstanding... I "guestimated" to use the 5gal rates on CIS-49 because 20L is almost equal to 5 gallons... aaaand there was NO information at all on the volume of each bottle in any forum that I have searched or any mixing volumes as well.

Look, I buy the 25 gallon size of Kodak Flexicolor developer/replenisher (KF 12-1532753) and I have these volumes of packaged concentrate to accurately report:

Part A = 3784 mL X 2 = 7568 mL total (need not be kept airtight)

Part B = 444 mL X 2 = 888 mL total (keep absolutely airtight)

Part C = 473 mL X 2 = 946 mL total (keep absolutely airtight)

I find that those amounts leave nothing 'left over' after mixed.- David Lyga

David, thanks for the info! So far, I've had my concentrates for about 2 years and they are still good! I do, however, keep them away from light and close them as soon as I get done measuring them out. I am going to look into the 25gal size. Is it economical for you?

Thanks! I was looking for this

I last bought the 25 US gallon size of Flexicolor (KF 12-1532753) about three years ago and paid about $140 delivered from Rochester to Philadelphia. I dilute so excessively that I might not need to ever buy more.

That said, I might make an addendum here: Part B of the Flexicolor just might NOT be required to be airtight. Part C, the actual developer, does, indeed, need to be kept airtight.

NOW WE CHANGE TO RA4:
While I am at it I will also post similar data for th Kodak RA4 Dev/Repl RT (Roller Transport) chemicals:

Part A: Orange color is normal and I think that this Part might NOT be required to be airtight

Part B: Absolutely MUST be airtight. MUST!

Part C: highly alkaline, to the point that storage in PET plastic will be disastrous because the plastic will crack and become too soft. Keep either in original container or glass. Does NOT need to be kept airtight, but a precipitate will form. My my experience is such that that precipitate can be filtered out and I see nothing has changed with the process. I am not a chemist, but, instead, a pragmatist: there seems to be no deleterious effect with losing this precipitate.

The metric quantities of the concentrate for this 'RT' version of RA4 are as follows for the 25 US gallon size (KP 36-8477184):

Part A: 2370 X 2 = 4740 mL
Part B: 1422 X 2 = 2844 mL
Part C: 2370 X 2 = 4740 mL

This RA4 presents us with a convenient ratio for mixing small quantities: ie, A:10, B:6, C:10. Simple!

The only issue I had with Ektacolor is that within just a few months time, Part B went bad on me, after opening it maybe twice, MAX. As far as the Flexicolor, I have used the "new" dilution and the color change is incredible. It did go from a blue to a yellow color fairly quickly, now it's just a darker blue and holds quite a bit longer before going to yellow... aaand the colors are much better! Anyway, thanks for these dilutions! I will have to keep note and use them in the future!

@Kanishka, glad this helped!
