Column Adapters

Column Adapters

Column Adapters are essential glass components used to connect different column sections, integrate auxiliary equipment, or transition between varying nominal diameters (DN). Constructed from high-quality borosilicate glass 3.3, they provide excellent chemical resistance, thermal stability, and durability, ensuring reliable performance in laboratory, pilot, and industrial-scale operations.

Standard column adapters are available with DN, DN1, and DN2 connections, allowing flexible assembly of glass column systems. Additionally, flat top column adapters are designed as headers for shell-and-tube heat exchangers and column systems, offering versatility in chemical, pharmaceutical, and petrochemical processes.

Custom sizes, with DN2 up to equivalent DN1, can also be manufactured on request, providing tailored solutions for specific process requirements.
