I just received a 3 neck 1000ml boiling flask that has a 1mm (diameter) dimple at the bottom of the flask. It appears that a VERY
small air bubble is trapped at the center. The flask holds fluid without leaking.
As a beginner, should I be worried about this compromising the integrity of the flask? The supplier is international...so I am just trying to make
sure that I don't need to ask for a replacement.
My intuition is that it is nothing to worry about...however I would appreciate some feedback.
Thanks.

nope. Its probably cheap glass but it should be fine. I buy cheep glassware and I have had no problems (bubbles in lots of them), and all my
glassware has been under vacuum. I have even gotten some name brand pieces which have bubbles.
I have never had a piece of glassware break on its own.

Bubbles aren't ideal, but they're not what you need to be worried about. Look instead for cracks, especially if you want to conduct reaction under
any kind of altered pressure.
