AP 3396Z Chemical Storage Bottle 2L

The collapsible design is genius—I just squeeze out the air after each use and my developer stays fresh for weeks. No more discarding half-used bottles of chemicals that went bad.

I was tired of my developer going bad after a few weeks, but this 2L bottle with the air reduction feature has kept my chemicals fresh for over two months now. The compression design is simple and effective.

After mixing a fresh batch of developer, I squeezed the bottle down until the liquid touched the cap and the air was completely gone. Six months later the stock solution still works exactly like day one. That air-reduction feature is worth every penny for anyone who doesn't process film weekly.
