Coiled condenser

Glass coiled condenser is used to cool and condense a gas back to a liquid, often as part of the process of chemical distillation

Soxhlet extractor - small

A Soxhlet extractor is laboratory equipment made of glass. Invented by Franz von Soxhlet in 1879. It has a flask, an extraction chamber, and a condenser. It can be used for solid-liquid extractions.

Thistle funnel - straight

A thistle tube is a piece of laboratory glassware consisting of a shaft of tube, with a reservoir and funnel-like section at the top. Thistle tubes are typically used by chemists to add liquid to an existing system or apparatus. Thistle funnels are used to add small volumes of liquids to an exact position.

Pressure equalising funnel

Used when liquids have to be introduced into vessels under vacuum. Also known as a dropping funnel which is a type of laboratory glassware used to transfer fluids. They are fitted with a stopcock which allows the flow to be controlled. Dropping funnels are useful for adding reagents slowly, i.e. drop-wise. This may be desirable when the quick addition of the reagent may result in side reactions, or if the reaction is too vigorous

Soxhlet extractor - large

A Soxhlet extractor is laboratory equipment made of glass. Invented by Franz von Soxhlet in 1879. It has a flask, an extraction chamber, and a condenser. It can be used for solid-liquid extractions.

Fractionating column

A laboratory fractionating column is a piece of glassware used to separate vaporized mixtures of liquid compounds with close volatility.

Graham condenser (Inland Revenue)

Graham condenser (Inland Revenue). Used for standard Inland Revenue test and control methods by brewers etc, the Inland Revenue condenser employs the use of coolant flow outside the coil. This condenser is very efficient but must not be used for fast rates of distillation. It is particularly useful for removing condensable vapours from non-condensable gases.

Thistle funnel - airlock

A thistle tube is a piece of laboratory glassware consisting of a shaft of tube, with a reservoir and funnel-like section at the top. Thistle tubes are typically used by chemists to add liquid to an existing system or apparatus. Thistle funnels are used to add small volumes of liquids to an exact position.

Specific gravity bottles

Specific gravity bottles determine liquid densities by measuring the difference between an empty and filled bottle and dividing by an equal volume of water to find the specific gravity of the substance. These bottles are also known as a density bottle or relative-density bottles.

Retort

A retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated. The neck acts as a condenser, allowing the vapors to condense and flow along the neck to a collection vessel placed underneath
