Description
Graham reflux condensers made from BORO 3.3 borosilicate glass provide highly efficient vapour cooling for continuous reflux and distillation work in chemistry, research and teaching laboratories. The internal spiral coil increases the available condensing surface area, allowing vapour to convert to liquid rapidly even when working with low boiling organic solvents. This makes the Graham design more effective than straight Liebig or simple jacketed condensers for workflows that demand stable and extended cooling performance.
The condenser is manufactured from BORO 3.3 borosilicate glass that conforms to ISO 3585 and aligns with ASTM E438 Type I Class A requirements for chemical resistance, thermal durability and low expansion. These standards ensure excellent resistance to acids, alkalis and organic solvents, along with reliable performance during repeated heating and cooling cycles. For Australian research and secondary school laboratories working with variable temperature reactions, the stability offered by ISO and ASTM compliant BORO 3.3 glass supports safer operation and longer service life.
The spiral coil design inside the outer cooling jacket creates turbulent coolant flow, improving heat transfer and maintaining a consistent condensation point throughout long reflux runs. Water connectors accept standard laboratory tubing and allow counter current cooling for improved efficiency. Standard ground joints integrate easily with reflux setups, botanical extraction systems, synthesis reactions and distillation assemblies without the need for adaptors. This ensures the condenser can be used across a wide range of organic chemistry, natural product extraction and process chemistry applications.
LabChoice Australia selects BORO 3.3 glass for its clarity, stress-relieved construction and compliance with international standards, providing dependable performance for Australian schools, universities and commercial laboratories. Each Graham condenser is annealed for stability, designed for secure connection with stands and clamps, and suitable for routine use in both teaching and advanced analytical environments. By maintaining ISO 3585 and ASTM E438 alignment, the condenser supports reproducible results, consistent cooling behaviour and long term reliability for demanding laboratory workflows.
