Liebig condenser. Designed to give turbulent flow in the water jacket with a comparatively slow rate of flow of coolant water by use of a small annular space. Description from https://www.austscientific.com.au/product/condensers/

Jacketed coil condenser. A double surface condenser having a coil as an inner cooling surface. This type has approximately twice the surface of a plain double surface condenser of the same effective length.

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.

Dufton fractionating column condenser. Dufton columns have an accurately fitted Dufton glass spiral which can be removed for cleaning purposes etc. This type of column has proved exceedingly successful in gas analysis. Description from https://www.austscientific.com.au/product/condensers/

Graham condenser - coiled type. The surface area is considerably greater than the corresponding Liebig condenser of similar dimensions. The coil condenser is extremely efficient in the reflux mode where counter-current cooling is possible. Description from https://www.austscientific.com.au/product/condensers/

Davies double surface condenser. Increased surface area and effectiveness compared with a corresponding Liebig condenser. Description from https://www.austscientific.com.au/product/condensers/

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 extraction condenser

Allihn condenser or "bulb condenser" or "reflux condenser" named after Felix Richard Allihn (1854–1915).
An inexpensive condenser, giving greater surface area than the corresponding Liebig type due to the bulb sections. This type is normally used under reflux. Description from https://www.austscientific.com.au/product/condensers/
