Medium-pressure columns

Medium-pressure columns are chromatography columns built to operate at pressures between the low backpressures of gravity and flash systems and the high pressures of analytical HPLC, typically from a few bar up to the low tens of bar. They separate compounds by passing a liquid sample through a packed bed, and are used across preparative purification, protein work and bioprocess development where larger sample loads rule out analytical-scale hardware.
