Chemistry

Wiped Blade Molecular Wiped Blade Molecular Distillation Unit Distillation Unit

The Wiped-Blade Molecular Distillation unit separates low-molecular weight compounds from a mixture.

It is used where the distillate has a high boiling point.

It has high vacuum capability hence reducing operating temperature, excellent mass and heat transfer and handles viscous fluids.

This process is used in many areas, including oleochemicals, biodiesel and polymers.

In the Biomaterials Research Group, it is particularly useful to distil our own polyol product.

Rotary Evaporator Rotary Evaporator

The RV 10 Digital rotary evaporator ("rotavap") removes solvents from reaction mixtures and can accommodate volumes as large as 3 litres.

It is equipped with a Chiller (Rotacool from Heidolph, Kelheim, Germany) and a heated bath.

The solvent is removed under vacuum, below its normal boiling point, which avoids over-heating the compound of interest, and is then trapped by a condenser and collected for reuse or disposal.

Gas Chromatograph with Gas Chromatograph with Flame Ionization Detector Flame Ionization Detector

(GC-FID)(GC-FID)The GC FID is used to analyze volatile lipid molecules and small modified lipid molecules.

Compounds ‘race’ through a column; some travel faster than others so the various groups exit the column at different times.

FID is a good general detector for organic compounds, able to detect at the nanogram level.

Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture.

Analytical BalanceAnalytical Balance

An analytical balance is used to measure mass to a very high degree of precision and accuracy.

The weighing pan of a high precision (0.01 mg or better) analytical balance is inside a transparent enclosure.

The enclosure is fitted with doors so that dust does not collect, and so any air currents in the room do not affect the balance's operation.

DesiccatorDesiccator

Desiccators are sealable enclosures containing desiccants (drying agents) used for preserving moisture-sensitive items.The items to be stored are placed on a platform, with desiccant in the space under the platform. A stopcock may be included to permit the desiccator to be evacuated.

A common use for desiccators is to protect chemicals which react with water from humidity; it also can be used to remove traces of water from an almost-dry sample.

Small Scale Simple Small Scale Simple DistillationDistillation

Simple Distillation is a method of separating mixtures based on differences in their volatilities in a boiling liquid mixture.

Distillation is a physical separation process, and not a chemical reaction.

It is used to separate a compound into more fractions for specific uses and also to remove impurities.

Column Chromatography Column Chromatography

A method for the separation of compounds from mixtures. Each compound is a fraction of the mix.

Eluent plus a stationary phase powder (such as silica gel) is poured into a glass column and organic material is added on top.

The individual components separate from each other while they are running through the column with the eluent, and each ‘fraction’ is collected.

Enables purification of synthetic products.

Thin Layer Thin Layer Chromatography Chromatography

(TLC)(TLC)Thin layer chromatography is another separation technique.

TLC is performed on a sheet of glass, plastic, or aluminum foil, which is coated with a thin layer of adsorbent material (silica gel, aluminum oxide, or cellulose).

Solvent is drawn up via capillary action; compounds ascend the plate at different rates and are separated.

This method is simple and capable of determining how many compounds are in the mixture.

UltraViolet (UV) UltraViolet (UV) LampLamp

An Ultraviolet Lamp is often used to visualize the compounds which have been separated by Thin Layer Chromatography.

A small amount of a fluorescent compound, usually manganese-activated zinc silicate, is added to the adsorbent that allows the visualization of spots under a blacklight.

The adsorbent layer will thus fluoresce light green by itself, but spots of analyte quench this fluorescence.

Soxhlet ExtractorSoxhlet Extractor

An apparatus for extracting compounds according to their solubility in differing solvent systems.

The solvent vapour travels up a distillation arm and floods into the chamber housing the solid. Some of the desired compound will then dissolve in the warm solvent. When the Soxhlet chamber is almost full, the solvent returns to the distillation flask by a siphon side arm.

It is an effective way to separate polymers from insoluble monomers, which have a limited solubility in certain solvent systems.
