Low-Pressure Chromatography Column

Low-pressure chromatography columns are pressure compressible glass columns designed for hygienic operation and simple, efficient loading, primarily for process development or biopharmaceutical production.

Patent column head sealing technology

• The lever-pressing sealing structure was used with high reliability, which prevents the problem that the pneumatic mechanism easy to leak and invalid.
• The expansion structure of pressurizing-down style gasket ring prevents column head departing from bed caused by the pull-up structure.
• Minimized Hold-up Volumes, Easy to clean and change the seal.

Patent column head rotating structure

• The column head rotates by the rotating screw of the column pipe, which is on the upper surface of the flange plate. After rotating in place, the second screw needs to be inserted. Media packing can be done after rotating the column head. It is easy to operate, without carrying out the column head.

Predictable linear scale-up

• Fix condition: Linear flow rate, buffer, packing material, bed height, sample concentration, pH, sample volume, and bed volume ratio.
• Scale-up condition: Column I.D., volume flow rate, sample volume.
