Shelf Life of Unopened Tetenal RA-4 Kit

[igmirien]

Hi guys,

I'd like to know what's the shelf life of an unopened Tetenal RA-4 kit.

Thank you!

Guess i've read on some Tetenal instructions.... one year unopened concentrate, opened concentrate 24 weeks, work solution 8-10 weeks

Thank you! I also sent an email to see what they say, not sure if they reply to emails.

For what it's worth, I had Kodak Ektacolor 3-part RA4 developer and 2-part bleach fix unopened concentrates that were 22 months expired. I wasn't optimistic they would be good but was very happy to find they were just fine. They were both to make 10 liters and I used all 10 liters (one shot use, as usual) to make many nice prints using the usual color filter settings and exposure times. I did use all the chemicals over a 6-week period, making up all the developer at once, in 1-liter bottles, and making up liters of bleach fix when needed.
