Seating and Removing a Solid Stopper
With no bore, this stopper shuts a vessel completely, which suits storing a solution or shaking a tube to mix it. Press it home with a gentle twist rather than knocking it down, and never close a vessel that is being heated, since trapped vapour builds pressure. To take it out, twist while lifting instead of levering it against the glass rim.
