• Made from ASTM E-438 Type-1 Class A, Boro 3.3 glass
• These Flasks comes with Ground Joint manufactured as per ASTM E-1404, Type 2, Class-1 requirement
• The Flasks are printed in white colour enamel

Here are some common uses:

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