Dynamic Axial Compression Column

Dynamic axial compression column (DAC) system, is the most mature area of preparative chromatography using the technology of packing column. The DAC column maintains its own pressure, discharges packing materials automatically, and functions as a high-performance liquid chromatography and column packing column machine. Using the DAC system can completely satisfy the continuity, uniformity, stability, and tightness requirements of the column bed and eliminate the influence of column bed collapse. DAC system is widely used in industrial purification processes, like peptide purification and natural chemical purification.

  • Manufacture with an independent design team to meet your different equipment requirements.
  • Liquid chromatography resins manufacture. Multiple liquid chromatography resins for different applications.
  • The complete technical solution for biochemical isolation and purification.
  • Best after-sale service. Installation, training, and spare parts provided.
  • Support equipment and complete solutions are available.



  • Using truss grinding in the column tube, increases the service life of the high-pressure sealing ring.
  • High-quality screen plate, provide the certificate.
  • A large preparative column sieve plate is convenient for loading and unloading with good sealing performance forced distribution.
  • The hydraulic cylinder is designed and manufactured by first-class manufacturers with a quality guarantee.
  • Multiple choices for the material contact with the fluid: 316 Stainless Steel/ PTFE / PEEK.
