Vacuum checkResolved

The audible vent is one of very few checks a purchaser can actually perform, and the article is right to bound what it establishes. — StopperingSteff (talk) 09:50, 24 March 2026 (UTC)

A vacuum was present and held. Not which gas, not whether the seal held for the whole shelf life. ✓ Done — BlankVialBo (talk) 13:25, 24 March 2026 (UTC)

Resolved. This thread is closed. Reopening it is fine if new sources appear; please add a new subsection rather than editing the closed discussion.

Two-stage stopperingDone

Partial seating during drying is the detail that explains why lyophilised vials have the stopper geometry they do, and it is rarely explained anywhere. — LyophilLena (talk) 10:30, 20 May 2026 (UTC)

It also explains why a lifted stopper on receipt is worth noticing. ✓ Done — StopperingSteff (talk) 14:05, 20 May 2026 (UTC)

Done. This thread is closed. Reopening it is fine if new sources appear; please add a new subsection rather than editing the closed discussion.
