Condenser (laboratory) A distillation setup using a Liebig-type condenser (the tilted double-walled tube at the center). A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point. The vapor is then cooled as it goes through the inner tube of the condenser. There it becomes liquid again, and drips into the ...
The Liebig condenser (/ ˈliːbɪɡ /, LEE-big) [1] or straight condenser is a piece of laboratory equipment, specifically a condenser consisting of a straight glass tube surrounded by a water jacket. In typical laboratory operation, such as distillation, the condenser is clamped to a retort stand in vertical or oblique orientation.
The Liebig condenser is simply a straight tube within a water jacket and is the simplest (and relatively least expensive) form of condenser. The Graham condenser is a spiral tube within a water jacket, and the Allihn condenser has a series of large and small constrictions on the inside tube, each increasing the surface area upon which the vapor ...
A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid. The vapor typically enters the condenser at a ...
A laboratory fractionating column is a piece of glassware used to separate vaporized mixtures of liquid compounds with close volatility. Most commonly used is either a Vigreux column or a straight column packed with glass beads or metal pieces such as Raschig rings. Fractionating columns help to separate the mixture by allowing the mixed vapors ...
Condenser. Cooling water out. Cooling water in. A Soxhlet extractor is a piece of laboratory apparatus [ 1 ] invented in 1879 by Franz von Soxhlet. [ 2 ] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the ...

A ST 45/50 ground glass inner (male) joint held above an outer (female) joint. The same joint, closed. Ground glass joints are used in laboratories to quickly and easily fit leak-tight apparatus together from interchangeable commonly available parts. For example, a round bottom flask, Liebig condenser, and oil bubbler with ground glass joints ...
