reflux condenser
A chemist attaches a reflux condenser to a round-bottom flask on a lab bench.
Noun: * A laboratory apparatus: A "reflux condenser" is a type of condenser, typically a glass tube surrounded by a cooling jacket, attached to a boiling flask. Its primary function is to cool vapors rising from a boiling liquid mixture, causing them to condense back into liquid droplets that drip back into the original vessel. This process prevents the loss of solvent and allows a reaction to be heated for an extended period without the contents boiling dry.
The term "reflux condenser" is used specifically in scientific contexts, primarily chemistry and laboratory settings. It describes a piece of equipment essential for a technique called "refluxing." * The chemist attached the reflux condenser to the round-bottom flask before beginning the heating process. * For this synthesis, you will need to set up the apparatus with a reflux condenser.
- Reflux (verb/noun): The technique itself is called "reflux." The apparatus facilitates the "reflux" process.
- The reaction mixture was refluxed for two hours. (verb)
- The solution was kept under reflux. (noun)
- Condenser (n): The general category of laboratory glassware used to cool vapors into liquids. A reflux condenser is one specific type.
- Liebig condenser (n): A simpler, straight-tube type of condenser often used for distillation, but which can sometimes be used for reflux in simple setups.
- Allihn condenser (n): A condenser with a series of internal bulbs, providing a larger cooling surface area, commonly used as a reflux condenser.
- Refluxing (gerund/n.): The act or process of using a reflux condenser.
- Return condenser: A less common but descriptive synonym emphasizing the function of returning condensed liquid.
- To set up a reflux: This phrase means to assemble the glassware (including the reflux condenser, flask, and heat source) for a reflux procedure.
- The first step is to set up a reflux with the starting materials.

- condenser such that vapor over a boiling liquid is condensed and flows back into the vessel to prevent its contents from boiling dry
