PET soda/softdrink bottles are cheap and close well. Therefore good for storing chemicals. So I would use that to carry or store your chemicals in. It might be a good idea to pack the bottles in a plastic bag first before putting them in your backpack, specially on the way home after putting the fluids back into the bottles. I only do B&W and keep stop & fix in 2L bottles and developper in a 1L bottle. At each printing session, I add 0.5L of freshly mixed developer and add that to the 1L "old" developer. At the end of the session, 1L goes back into the bottle (no air) and the rest down the drain. Works fine and less developer goes down the drain that way. If you do the same you would have to carry 4 bottles in your backpack; 3 PET with old dev, stop and fix and 1 bottle with developer concentrate. Storing B&W chemicals at room temperature is fine. Just keep them in the bag/dark at work.
