Condensers are laboratory glassware components used to cool vapours and return them to liquid during reflux, distillation, solvent recovery, Soxhlet extraction, and essential oil separation. The range shown includes air condensers, Allihn bulb condensers, Davies double-surface condensers, Dimroth coil condensers, Friedrichs condensers, Graham coil condensers, Liebig condensers, West condensers, jacketed coil condensers, angled reflux condensers, extraction condensers, fractionating columns, and specialised receivers.
Allihn, Davies, Dimroth, Friedrichs, Graham, Liebig, and West designs provide different vapour paths and cooling surface arrangements. Allihn bulb condensers offer an enlarged internal surface for reflux work, while Liebig and West condensers provide a straightforward jacketed tube design for routine condensation. Dimroth, Graham, Friedrichs, Davies, and jacketed coil models increase vapour contact with cooled surfaces for workflows requiring more efficient reflux or vapour recovery.
The extraction range includes Allihn condensers for Soxhlet work, Dimroth condensers for Soxhlet apparatus, and a complete Soxhlet Extraction Set with Allihn Condenser. The Clevenger Condenser supports compatible Clevenger apparatus used for essential oil extraction and hydrodistillation. These components should be selected according to the extraction body, flask capacity, ground joint size, cooling requirement, and laboratory method.
The category also includes a Hempel Distillation Column and Vigreux Fractionating Distillation Column for improving vapour-liquid contact during fractionation. The Reflux Separator Receiver with PTFE Stopcock supports controlled collection or separation within compatible reflux and distillation assemblies. The Ether Cooling Condenser and angled reflux condenser provide additional configurations for specialised cooling and apparatus layouts.
Most products in this range are manufactured from BORO 3.3 borosilicate glass, offering low thermal expansion, chemical resistance, and clear visibility during heating and condensation work. Compatible ground joints help integrate the condenser with flasks, extraction bodies, receivers, and adapters. Joint size, effective length, coolant connection, vapour direction, and apparatus compatibility should be checked before ordering.
For water-cooled condensers, coolant is normally introduced through the lower connection and discharged from the upper connection where this matches the manufacturer’s design. This helps keep the cooling jacket filled during operation. Glassware should be clamped without placing stress on the joints, flexible tubing should be secured, and sudden temperature changes should be avoided.
ISO 4799 specifies several laboratory condenser designs, including Allihn, Liebig-West, coiled distillate, coolant-tube, and double-section condensers. ISO 3585 defines the material properties of borosilicate glass 3.3. ASTM E438 covers glass types commonly used in laboratory apparatus, while ASTM E676 covers the dimensions and tolerances of interchangeable taper-ground joints. These standards should only be presented as product compliance claims where confirmed by manufacturer documentation.
For LabChoice Australia customers, Condensers provide a broad BORO 3.3 glassware range for chemistry laboratories, universities, research facilities, pharmaceutical development, environmental testing, teaching laboratories, and industrial quality control workflows involving reflux, extraction, distillation, cooling, and solvent recovery.
