The DAC column, developed for laboratory, pilot, and industrial use, features a hydraulic cylinder that continuously compresses the packing layer, preventing any voids in the column. There are two types available: one that compresses the column from the top and another that compresses it from the bottom.

Product Features

· The column performance is excellent due to the application of uniquely designed distribution and collection plates developed with special processing technology.

· Standard prep HPLC columns may develop voids over long-term use. However, the DAC column continuously compresses the packing layer with a piston head at a constant pressure, preventing voids from forming even after prolonged use, thereby extending the column's lifespan.

· The packing can be automated using a slurry automatic feeding device.

· Both compressed air and electricity can be used as power sources for the cylinder. Using a pneumatic pump allows for sufficient pressure during packing, maintaining the column's performance over an extended period. Additionally, if the noise from the pneumatic pump is bothersome, an explosion-proof electric drive motor can be utilized.

· When packing a DAC column with a diameter of 800mm or more using a pneumatic pump, there are limitations on flow and pressure, which can result in longer packing times. In this case, a hydraulic station can be used for rapid column packing. After packing, a pneumatic pump is used to maintain the pressure.
