Developer storage - not glass
I find the idea of fractioning developer in many small containers ready for use not practical, mainly because it's difficult to find small containers that hold exactly the quantity that I need when filled to the brim.
I find it a better idea to fill 1 L glass containers to the brim (which is slightly more than 1L) for storage, and then pour the rest in something like a floppy tank [see image] where air can be squeezed out.
I would do the same when needing more developer, breaking open a 1 L container and empty it out in the floppy bag.
I think many people are against plastic squeezable containers, but these floppy bags squeeze better than accordion bottles and in any case since they hold 2/3 doses, content will not have many chances to oxidize before the container gets empty.
Does anybody have an idea about where to buy these?
