If one manufactures chromatography column tubes from plastic/thermoplastic or composite materials (such as polypropylene (PP), polyethylene (PE), polyamides, acetals, or glass-filled plastics, such as glass-fiber plastics) and secures at least one of two flow distributors within the column tube with a tight interference or press fit, the resulting chromatography columns reduce or avoid the formation of dead zones around the press fit flow distributor and have an infinitely adjustable packing medium volume, also known as the medium "bed height." |
