Here are some common uses:

1. Distillation:
   • Conical flasks with ground joints are commonly used in distillation setups. The ground joint allows for a tight connection with a distillation head, condenser, and other components, ensuring efficient separation of components based on their boiling points.
2. Fractional Distillation:
   • For precise separation of components with close boiling points, these flasks are utilized in fractional distillation setups. The ground joint ensures a secure connection with the fractional column and other distillation apparatus.
3. Refluxing Reactions:
   • The flasks are employed in reflux setups where a condenser is attached to the ground joint. This allows for continuous refluxing of the reaction mixture, preventing the loss of volatile components.
4. Vacuum Filtration:
   • The ground joint on the conical flask is suitable for vacuum filtration setups. It provides a secure connection with the filtration apparatus, allowing for efficient separation of solids from liquids under reduced pressure.
5. Chemical Synthesis:
   • Conical flasks with ground joints are used in various chemical synthesis processes where a tight and secure connection with additional glassware, such as condensers or reflux systems, is required.
6. Heating with Attachments:
   • The ground joint allows for the secure attachment of heating mantles or other heating devices. This ensures controlled and uniform heating of the flask contents.
7. Solvent Evaporation:
   • In setups where solvent evaporation is needed, the ground joint on the flask allows for the secure attachment of a condenser or other apparatus to collect and condense evaporated solvents.
8. Pressure Reactions:
   • The ground joint is beneficial in setups involving pressure reactions. It allows for the attachment of pressure-equalizing additions or monitoring devices securely.
9. Synthesis and Reaction Monitoring:
   • These flasks are used in synthetic chemistry and reaction monitoring where additional monitoring equipment or sensors can be securely attached to the ground joint.
10. Customized Setups:
    • The presence of a ground joint adds versatility, allowing scientists to create customized experimental setups by securely attaching various glassware or equipment as needed for specific experiments.
