Refractometer calibration solution

Does refractometer calibration solution expire?

I would assume not if it doesn't have an expiry date on the bottle. I have had mine for years and had never considered it may expire. Either way, I give it a good shake before I use it.

No, but it might evaporate if left open too much.

check out the thread I just posted, I'm seeing some odd results with different brands of brand new testing solution.
