DAC Dynamic Axial Compression Chromatography Column, Constant Bed Pressure (CAT#: STEM-BC-3067-ZJF)

The DAC dynamic axial compression column is designed for packing, compressing, operating, and unpacking preparative chromatography beds. It can automatically maintain pressure on the packed bed throughout chromatographic operation. Constant axial compression helps preserve bed continuity, uniformity, stability, and compactness. The technology reduces the risk of column-head collapse and bed loosening during use. Rapid packing shortens preparation time before separation. The packed column can provide high efficiency and repeatability approaching analytical-column performance. Large-diameter preparative columns can be packed while maintaining stable separation performance. Optional injection pumps, injection valves, switching valves, and pressure-protection devices can be integrated. Automatic or manual fraction-collection systems can be configured according to the process requirement.
