How long Kodak Flexicolor Lorr LU part C concentrate can be stored in open bottle ? When I buy new pack Bottles not being sealed and after 2 month part C is still yellow colour

LU has longer lasting power than regular LORR, I just have Flexicolor, that has a 2005 expiry date iirc (or was that the E-6), anyway its been open since last year, it's fine. LU will be even better.

Part C is the one that won't last. If it is showing a gray color it is going bad. It will eventually turn black and will be junk.If you have yours since 2005 and if it is still good use it soon. It will not last for too long any more. I have quite some LORR developer that the Part C bottles look black now. I thought of donating some of them to schools but it was too late. Anyone knows where to get Part C only of the LORR developer?

Here i have tested developing with fresh part C and part c who was muddy and black and had to be rinsed trough a coffe filter. Ill Guess Photo engineer can say a bit about the curves. My conclusion is that the film is flat, dense and probably gives funny colours.
