Dynamic axial compression columns are the most mature areas of preparative chromatography using the technology of packing column, dynamic axial compression columns can be self-loading, maintain their own pressure, discharge column by oneself, have the function of the chromatographic column and packed column machine, using DAC loading of the chromatographic column can completely satisfy the continuity of the column bed, uniformity, stability, and tightness requirements, eliminate the influence of the column bed collapse.
In 2005, Hanbon Sci&Tech developed the first dynamic axial compression column with independent intellectual property rights in China, and has built the largest dynamic axial compression column production and assembly workshop in the world. After continuous upgrading, it has been recognized by the international market and exported to more than 20 countries including India, South Korea, Norway, Hungary and Germany. The inner diameter range of dynamic axial compression column is from 50mm to 2000mm, which can also provide customized service.
