Reading the product description, I see that the QLT Ulano emulsion lasts for approximately 3 months if kept at a temperature of 5°C or lower. If I bought some extra pots and made sure that I kept them cool and unopened, how long would they last?

The QLT Ulano emulsion, in an unopened container, lasts for approximately 1 year at 20°C.

Once opened, if kept refrigerated at 5°C, it should last up to 90 days.
