I usually use the Tetanol kit that does a dozen or so rolls at a time. When I have a batch ready to develop, I mix the chemicals and have a developing session. I can't tell you how long it's good for when mixed, but when I'm working with C41, I do things the opposite way. Try also Fuji Hunt Express C41 kit or Rollei Digibase C41 kit (they say this is a smaller version of Fuji kit) I am just collecting a batch of C41s now to try Rollei kit I've been using Tetanol kits but I'm interested in something with a good life when mixed, and developing the extra rolls for my money. It's the only size they have so no other options, Their liquid kit is for the same amount (quart/liter) I have the liquid kit waiting to be mixed when the powder kit batch is depleted. It's their powder kit on their own site listed as a kit for a Quart or one liter.īeing a EU citizen It means I have one liter developer made from the powder kit. It's Cinestill CS41 that your using, is it ? The films were a Fuji Superia 200 (Expiry date 12-2014) and a Fuji Superia Xtra 400 (Expiry date 06-2019) Will have to scan but sofar the negatives do look good That's the batch I made in October (the 13th) 2019. How long? Is this different that other developers? I think I am safe to assume from what I have seen from others that I have months to use the mixtures which is good enough for me.Īnd today I developed films number 26 and 27 with the same batch developer "- Long lasting shelf life with 3 part Developer and Blix mixtures" I was looking at Freestyle's website and at the Cinestill products and saw this: I don't know how used working solutions keep up because there is additional degradation due to developer exhaustion and oxidation induced by agitation. Regarding the Blix, opened concentrates have normally a very good shelf life. You can do it just with the Part C or with the mixed working solution, what suits you better. The capacity of the bottles should match the amount of chemistry you use per batch.

The most important thing with CD4 is to avoid the contact with oxigen, so try to keep it always in smaller bottles full up to cap. It is where the developer agent is (CD4), the rest of parts contains additives with excellent shelf life. The only component you should care about is the Part C of the developer.
