I bought a large 30ml bottle, which seems like it will last a long time. Will it expire?

The official lifespan is 28 days, but I've kept it in the refrigerator for two or three months and it's still working fine.

As long as you follow aseptic techniques when pumping water and avoid contamination, it will be fine.
