Distillation glassware is used when separating liquids from one another, using the differences in boiling point between the individual components. We have a variety of different size distillation equipment in teaching labs.

Dean-Stark apparatus is used to remove water from a less dense solvent. The cone end connects to the reaction vessel and the socket end connects to a condenser. The stopcock is used to remove excess water as needed during the process.

Dropping funnels are used to control the flow of a liquid reagent into a reaction, where addition must be carried out slowly. The rate of addition is controlled using the tap. 

A Soxhlet extractor is used when a compound has limited solubility and any impurities are insoluble. The chamber fills with warm solvent and when a level is reached it siphons back into the heating flask, along with some of the desired compound.

Dreschel bottles are used as oil bubblers when carrying out air sensitive chemistry, for example in a schlenk line. Silicon oil is added to the bottle and the head attached to the line, creating a constant nitrogen flow .

Desiccators are airtight containers which keep hydroscopic chemicals dry by maintaining a low humidity atmosphere through use of a suitable drying agent. 

A Kjeldahl flask is a round bottom flask with a long neck. It is used in Kjeldahl digestion which is a process used to determine the amount of organic nitrogen in a chemical substance.

A viscometer is used to measure the viscosity of liquids.

Splash head adapters are used during distillations or rotary evaporation to prevent contamination or prevent loss of product. They catch any liquid that has 'bumped' out of the collection vessel and allow it transfer back.

Flash columns are the most common form of column chromatography used in teaching labs. They are used to separate components of a mixture, to purify a product, relatively quickly.

Other shapes and sizes of columns may be more suitable for purifying different products.

Schlenk Lines are used to carry out air-sensitive chemistry in an inert environment. Reactions are typically carried out in a Schlenk tube which is connected to the Schlenk line using thick-walled rubber tubing.  

Gas lines offer a means of manipulating gases in the laboratory in order to study their properties, commonly using infrared spectroscopy.

After using a rotavap or büchner funnel to remove solvent from a compound it may appear dry but often there will be residual solvent molecules that can only be removed by placing the compound under high vacuum.
