This particular version is the most-widely used design for 2 mL vials. It is compatible wth all wide-opening 2 mL glass and polyproplene vials, 2 mL micro vials and 2 mL High Recovery vials. While it is the most common option for 2 mL vials a close second are snap top style vials, however, they are less common.
