Brief introduction: At present our company launched DAC dynamic axial compression system is the most widely used in the area of industrial preparation of chromatographic column, usually chromatographic column diameter greater than 100 mm must choose DAC dynamic axial compression system, take the DAC dynamic axial compression technology to prevent the collapse of the bed body or eliminate the influence of the bed body collapse. Conventional axial compression technology is very difficult to fill out the tall secretory effect of chromatographic column. Can only adopt dynamic axial compression technology referred to as "DAC, it is regarded as the only can maintain good in all kinds of size of column chromatography separation effect of technology, is also the best preparative chromatography and packed column technology, advanced preparation of DAC dynamic axial compression column system with their own column, column pressure, to discharge column, with the function of the chromatographic column and packed column machine, using DAC loading of chromatographic column can completely satisfy the continuity of bed layer, uniformity, stability and tightness requirements. DAC dynamic axial compression column preparation system, its principle is through the up and down movement of the piston packing column, column pressure and discharge column, the piston is equipped with a specially designed sealing ring around allows the piston top and bottom slide freely, at the same time to maintain a higher sealing pressure. The piston movement and hydraulic pressure stable by evenly. Dynamic axial compression system separation effect of different diameter and was equal to that of analytical column separation efficiency. Features: 1. The structure of the leading design, convenient operation, small size, beautiful appearance, etc; 2. The piston speed fast and smooth, uniform flow distribution, good sealing performance, high pressure, pressure holding time is long, etc.; 3. The loading process is easy to learn, loading time is short, high column efficiency, good reproducibility, almost close to the analytical column column efficiency; 4. DAC technology to constant continuous pressure of chromatographic column bed, effectively avoid the stigma collapse and loose bed; 5. Can satisfy the use for a long time, if the chromatographic column once contaminated, discharging easily and conveniently, fill again; Can also be repeated loading, greatly extend the service life of the chromatographic column. 6. The same system of packing column support itself DAC dynamic axial compression column diameter or less of a variety of specifications of chromatographic column packing; 7. Packing good chromatographic column from the system of packing column used independently and can still maintain the stability of the column bed and the original column efficiency, convenient movement and use; 8. The overpressure protection, can fully ensure the safety of users; 9. Selling price is only a third of the similar imported products, even lower.
