Matching a Lid Configuration to Your Reaction Vessel
These lids are designed to sit on a flat-flange reaction vessel and provide multiple angled and parallel ports for stirrers, thermometers, addition funnels and other fittings around a central connection. The three socket-size configurations let a buyer match the lid to the specific joint sizes already used on their reaction flask or vessel, rather than needing a custom fit.
