Kodak Flexicolor III Replenisher
I tool the plunge while it is still possible to do so and purchased the 12.5 gallon kit of Bleach III, Part A and Part B along with the Bleach Starter. So I won't have to worry about buying C-41 bleach at a reasonable cost for several years. Here's my questions:
1. Instead of mixing 12.5 gallons of replenisher, I'd like to mix say 1 gallon at a time. If I do this would it be better to mix a 1 gallon working tank solution with starter or just 1 gallon of the replenisher and make a working tank olution as I need? I guess my real question is will the working tank solution have a shorter "shelf life" than the mixed replenisher?
2. The chemistry came in blatter containers in which a kodak screw cap dispenser is used to dispense the chemistry. Does anyone have one they would like to see or know where I can get one?
Thanks for your help.
PS: The stockhouse I purchased from will ship and is located in LA and has 1 kit left. My total cost with shipping and tax was $232.00. PM me for their contact information if you're looking to purchase the same.
I think the keeping properties of c 41 bleaches are very good and if you process a reasonable amont of film you won't need to worry about it going bad.
I'm sure PE will answer with more specifics but I dout you wil have a problem
On a side note, I had problems sourcing the starter and just omitted it on the advice of members here and have had no issues due to lack of the starter.
Thanks for the reply Bruce.
I don't expect the unmixed bleach to go bad (when I asked Kodak they responded with a 5 year shelf life but I'm sure that's the fall-back to length of time as they couldn't come out and say "indefinite" for obvious reasons) but what I am uncertain of is whether or not this particular bleach, when mixed as a tank solution ready to go, will last as long as their ready-mixed product. In other words did they add any ingredients to the latter to increase its shelf life? Rather than mixing a gallon of Replenisher, I'd rather mix a gallon of tank solution ready to use.
BTW, you can get the starter from Calumet.
I have seen the unmixed and mixed bleach both survive for 5 years or more.
As for starter, it is not really needed with the bleach. It is used to just tweak the pH.
I ended up with some off brand imitation Bleach III off ePrey that was fairly cheap so I scarfed up 10 gallons and it has been discontinued.
They had their own starter but after asking here I just decided to say screw it and run some tests/expired film through it but it works well and I replenish a half gallon working solution and then I pull what I need for a dev session from that 1/2 gallon.
The nice thing about it is that you don't have to worry about oxidation/air with the bleach as I understand it and the Kodak Bleach III even calls for aeration... so I shake my bleach once in a while but I'm running small inversion tanks so I figure it gets aerated with agitation.
(holy runon sentence batman)
Wonder what we'll do when the Kodak stuff gets discontinued.
Your experience just goes to show what a hassle and expense it is to get now.

If it gets discontinued, I just happen to know the formula!
Thanks for the replies.
I'm going to mix it as a tank solution by the gallon. That's how I use to purchase it before they discontinued the 1-gallon ready to use product which cost ~$25.00/gallon. I'll have to mix this but the the price of 1-gallon drops from the $25 range to $17.47 or $4.60/Liter - not enough of a saving to motivate me to switch before they discontinued the ready to use product - but surely now when the replacement cost me $38.95 + tax for 2.7L or $15.83/Liter!
PE: Don't forget to post that formula on this forum when it is discontinued or you, heaven forbid, pass away. Make sure that is in your will!
You could always go with a ferricyanide bleach. Easy to buy and mix and cheaper.
Now if only we could find a source for the chemicals... I'm having a hell of a time finding ferric ammonium EDTA (much less the PDTA that's used in bleach III). I managed to accidentally order ferric ammonium sulfate from the photographers formulary instead of EDTA; they don't seem to carry ferric ammonium EDTA anymore.

The only other place I found that sells it is in china, and they only sell it by the 250kg barrel or more!
But the process is far more complex. You need an set of washes and a clearing bath.

Anyhow, I know how to get around that.
