Boling Flask, Short Neck, with Joint, Flat/Round Bottom

Description

A single-neck round-bottom flask is one of the most commonly used pieces of glassware in laboratories, especially in chemistry and chemical engineering. The round-bottom shape facilitates uniform heating, while the single neck provides one connection point for various apparatus.

 Purposes

1. Heating and Reactions: The round-bottom design allows for efficient heating due to the even distribution of heat across the curved surface. It is ideal for reactions that require consistent or elevated temperatures.

2. Distillation: It is widely used in distillation processes where the flask can hold liquid that is heated and vaporized.

3. Evaporation: Used for evaporating solvents or other liquids under controlled conditions, often in combination with a condenser.

4. Synthesis: The flask serves as a container for chemical reactions that involve reagents, particularly in organic synthesis.

5. Solvent Addition or Withdrawal: It can be used for the addition or removal of solvents and other liquids via a dropper or burette connected to the neck.

Typical Applications of a Single-Neck Round-Bottom Flask

1. Organic Chemistry:

   • Used in many standard organic reactions that require heating, such as refluxing, condensation, or hydrolysis.

   • Frequently used in distillation setups for separating solvents, extracting essential oils, or purifying liquids.

2. Refluxing:

   • The flask is often paired with a condenser for reflux reactions, where the liquid is heated to the boiling point, then condensed and returned to the flask to continue the reaction process.

3. Distillation:

   • A key tool in simple or fractional distillation to purify liquids by separating components based on their boiling points.

4. Synthesis of Chemicals:

   • Often used in the synthesis of organic compounds where controlled heating and the introduction of reagents are required, such as in esterification or grignard reactions.

5. Evaporation:

   • The flask can be used for the evaporation of solvents in a rotary evaporator setup, where the solvent is gently heated under reduced pressure to prevent decomposition of sensitive materials.

6. Vacuum Filtration:

   • It is sometimes used in vacuum filtration setups to hold the liquid being filtered under a vacuum to accelerate the process and increase purity.

7. Solvent Recovery:

   • In industrial settings, it is used in solvent recovery systems, where it holds liquid waste or solvents that need to be distilled or evaporated for recycling.
