The interactive lab primer - using a rotary evaporator

No comments

A rotary evaporator is used to remove large amounts of solvent from solutions at a reduced pressure. This is often done to isolate a product from a chromatographic separation or a solvent extraction.

Column chromatography

The separation of mixtures produced in chemical reactions is often carried out by passing the mixture through a stationary phase of silica held in a column. Solvents move compounds at different rates through the silica allowing them to be separated into fractions by collecting the emerging solvent. This can ...

Heating under reflux

The term ‘reflux’ describes an arrangement in which a reaction is carried out in a boiling solvent with the vapour being condensed and returned to the reaction vessel. Refluxing is carried out when reactions need to be heated to give a reasonable yield of product in a reasonable time. ...

Drying liquids

There are many instances when it is necessary to remove traces of water from a solution or liquid. One common example is the drying of an organic layer after a solvent extraction. The technique involves adding a suitable solid drying agent to the liquid followed by its removal by gravity ...
