Fractional distillation

Fractional Distillation is used to separate compounds with boiling points that are close. Video: Fractional distillation video
Resource
Using a rotary evaporator

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. Video: Using a rotary evaporator video
Resource
Running an infrared spectrum

Infrared (IR) spectroscopy is a technique which reveals the bonds present in a compound and therefore can be used to identify functional groups. A sample of reaction product can be analysed to confirm its composition by comparison to a pure sample, or to judge the extent of reaction by comparison ...

Hot gravity filtration

This is the simplest kind of filtration when the solution to be filtered is poured through a filter paper in a filter funnel. The filtration of hot solutions through a funnel and fluted filter paper is often carried out as part of a recrystallisation. Gravity filtration is generally carried out ...

Clamping Quickfit glassware

There are many different ways to assemble apparatus and it is important that you carefully follow the guidelines that might be in the practical script. This section illustrates the basic principles and good practice involved in putting together Quickfit glassware. Video: Clamping Quickfit glassware video
Resource
Vacuum distillation

Vacuum distillation is a distillation carried out at reduced pressure to lower boiling points. This is particularly useful for distilling products of boiling points over 100oC. Video: Vacuum distillation video
Resource
Heating

There are many instances when heat is needed in a laboratory practical, it is needed to reflux reaction mixtures, to distil liquids as well as help to dissolve solids in recrystallisations. The use of the appropriate method of heating is most important.
