Should culture flasks be sealed with airtight caps or vented caps?

Publication date：2026-10-29
Page views：
That’s fine. When using culture flasks with sealed caps, screw the cap on to about two-thirds of the way—do not tighten it completely—leaving roughly one-third of the space open to allow for gas exchange. Some brands of sealed-cap flasks have alignment marks on the caps to indicate the proper position.
