rollei digibase c41 - old chemistry still useable?

[wilfbiffherb]

ive got a pack of half used chemistry thats been opened for around a year - do you reckon its still useable or should i not bother? ive been shooting mostly black and white for ages but ill been doing some colour later on this afternoon.

Check the colour of part 3 of the developer. As long as it is clear to light straw colour you should be ok. If it has gone dark brown/purple it has oxidised.

I used some year old concentrate where part 3 had been fridge stored for about half the time. It was absolutely fine and has produced nice results.

I found out yesterday that my Part C/3 had oxidized (dark, almost black, with dark grain in the liquid). Now, I've got a Fuji Hunt kit with a few liters worth of bleach, fix and stabilizer. A year after opening, can I expect those solutions to still work reliably?

just checked - blacker than a miners thumb! out it goes!

Save the bleach!

My part C went bad very soon after opening the kit (even though I top off my chems with gas) so freestyle sent me three replacements. I opened those today to find all three dark purple. Meanwhile my kodak stuff that's four years old is just fine. Don't buy this crap!

Four years. That's amazing. Curious, how are you storing it?

Never had any problem with part C of the color dev. My kit is open since March and today I did my last working solution and part c was still clear!

I shoot some "wine preserver" in each bottle before screwing the lid on. Amazon sells it in cans. I might just be lucky too but the negs I did this morning look pretty good on my monitor.
