I am using a Morse tank/hanger negative developing system that holds ~7 liters of chemical in each tank. I generally batch process a large number of negatives with D-76 at 1:1 and pitch the developer/fixer after I am through in order to work with consistent, fresh chemicals. I will be shooting a little differently in the coming weeks and would like to process smaller batches of negatives. This has led me to store my chemicals and re-use them. I have some cast-off amber glass 1 gallon jugs from work that I will be using. They seal nicely, but one of the jugs will only be half full (or is it half empty?). I have heard that one could use glass beads (those little dime sized decorative glass balls used at weddings, etc.) to fill up the volume to eliminate the air in the container.
It seems the only glass beads I can find have a glimmering coating on them. Does anyone know if that will react with the developer (D-76 at 1:1) or fixer (Kodak rapid fixer)? I really strive for consistency and don't like tossing monkey wrenches into my system.
Thank you in advance for any imput into this issue.
