Overview
Glass flasks with a conical profile and rubber stoppers make up this Pyrex set, covering small, medium and larger volumes. Each flask has a round bottom, and the stoppers let samples be stored or shaken.
Getting three sizes together suits a teaching lab that needs a spread of volumes. The listing is brief, with no neck size, graduation marks or dimensions.
Who it's for
Classrooms and general labs wanting a starter selection of flasks with stoppers. Precise measurement work belongs with volumetric ware.

Performance notes
The conical shape lets liquid swirl without splashing, which is why Erlenmeyer flasks are used for mixing and titration. The rubber stoppers seal the neck for storing or gently shaking contents.
