A flask is a versatile laboratory container, typically made of glass, designed to hold, mix, heat, cool, or store liquids and solutions while conducting experiments.
Common Types of Chemistry Flasks
| Flask Type | Shape & Features | Typical Uses |
|---|---|---|
| Erlenmeyer Flask | Conical body, flat bottom, narrow neck | Mixing, titration, heating, culturing |
| Volumetric Flask | Pear-shaped with a long neck and calibration mark | Precise preparation of standard solutions |
| Round-Bottom Flask | Spherical body, often with one or more necks | Heating under reflux, distillation, synthesis |
| Florence Flask (Boiling Flask) | Round body, long neck, flat or round bottom | Boiling liquids, uniform heating |
| Büchner Flask (Filter Flask) | Thick-walled with side arm for vacuum | Filtration under reduced pressure |
| Schlenk Flask | Round-bottom with side arm and stopcock | Air-sensitive reactions under inert atmosphere |
