The best thing I've ever found to keep air out of solutions to prolong their sto rage life are plastic Cubitainers...(the things that Sprint Systems package their products in) with spigot caps. As the solution is gradually used..atmospheric pressure squeezes the container in so air stays out. This dramatically prolongs the life of any kind of oxygen sensitive solution. Before he died several years ago I was f ortunate to talk my good friend and mentor Paul Krot into selling me a supply of new, unused, empty Cubitainers , but I will need new ones @ some point soon. Apparently Paul went thru a lot to get access to them originall y when he designed Sprint packaging (I believe they are made by Heico)..so Sprint is still (very understandably) r eluctant to go into the empty container business. If anyone can locate a source for new, unused Cubitainers..with o r without the boxes..they would be doing the Photo world a major favor...Anyone???
