I'm looking for a fixer that I can take to South America by plane. I usually use TF-4 or TF-5 from the formulary, but I don't think flying with a liquid fixer is a great idea. I also don't think I can buy it on the ground. Is there a fixer than I can mix from powder that is alkaline? I'll be using XTOL and Acufine, and would prefer not to use hypo clear, just dev—rinse—fix—rinse like usual. I'm taking Tri-x and Tmax 3200 btw.
