How old can samples be?

I have some oil samples in bottles that I got about 2 months ago. Are these too old to sample? They have been sitting in the Blackstone sample bottles. I wonder if something from the bottles could have leached into the oil.

If the lid has been kept tight, they will be fine.

Thanks! They have been.
