功能

• One of the most common "reflux condensers."
• It is d in combination with other glassware, mainly during distillation and reflux (refluxing).
• Cooling water flows outside the double-pipe structure to cool it, and steam cools inside to condense (liquefy) it.
• Since the inner tube is straight and cylindrical, condensate does not accumulate even if it is slanted, it is often d in the slanted state.
