Hempel Distillation Column Plain BORO 3.3 Borosilicate Glass

Hempel distillation column plain design provides a stable and efficient vapour separation pathway for general laboratory distillation, solvent purification, and analytical chemistry workflows. Its straight, unpacked internal column allows vapour to rise cleanly through a controlled vertical pathway, supporting predictable reflux behaviour and consistent fraction separation when paired with external heating mantles or round-bottom flasks. This classic design is widely used in Australian teaching laboratories, research facilities, and industrial QC environments because it offers dependable performance without the complexity of structured packing or vigreux indentations.

Constructed from high-clarity BORO 3.3 borosilicate glass, the Hempel column supplied by LabChoice Australia maintains excellent chemical durability and thermal stability during repeated heating and cooling cycles. BORO 3.3 glass meets ISO 3585 requirements and aligns with ASTM E438 Type 1 Class A glass specifications, ensuring resistance to thermal shock and harsh chemical vapours, including acids, bases, organic solvents, and high-temperature distillation media. This material reliability supports safe usage in continuous distillation setups, fractional distillation systems, and pilot-scale teaching rigs.

The plain Hempel design is often selected for simple or moderate-complexity separations where a smooth internal surface is preferred for unobstructed vapour rise and minimal hold-up volume. In many academic and industrial labs, this column provides an ideal balance between efficiency, cleaning simplicity, and cost-effective operation. Its compatibility with standard ground glass joints ensures easy integration with condensers, stillheads, and other glassware components within existing distillation assemblies. LabChoice Australia supplies each column with precise joint tolerances and transparent manufacturing quality control, ensuring a leak-free seal and dependable long-term performance.

Whether used for purifying solvents, separating liquid mixtures, training students in distillation fundamentals, or supporting routine R&D workflows, the Hempel distillation column plain offers a reliable and technically accurate solution for Australian laboratories. Its robust BORO 3.3 construction, universal joint compatibility, and simple maintenance requirements make it a trusted choice for institutions that prioritise long service life and consistent distillation results across a wide range of applications.
