A few days ago I heard from some friends that they store all their stock solutions (Xtol and other developers, too) in bag-in-box containers that they purchased from a supplier of wine cellars and apple juice producers. Their report was quite simple: it works very well, chemistry lasts very long and using it is simple. As a nice bonus, prices are ridiculous, a bag and box for 5 liters costs around 2 Euros (2.70 USD). I know these bag-in-box containers from my odorless fixer, Amaloco X89, but never thought about getting such containers for my Xtol. Is that a popular way of storing chemistry in your photo labs?
