    The newly released Biotage® Selekt flash chromatography instrument can be run at a maximum flow-rate of 300 mL/min or a maximum pressure of 30 bar. These high flowrates and pressures enable a user to perform chromatography using not only dry-packed, single-use plastic flash columns containing small (≥20 μm) spherical silica particles, but also semi-preparative, slurry-packed
    HPLC columns for multiple use with smaller (≤20 μm) spherical silica particles.

    When Isolera™ was launched, the maximum system pressure that could be reached was 10 bars, but reaching that pressure was a challenge since most of the Flash columns could not withstand the higher pressures. The maximum pressure rating for the Biotage® SNAP columns, for example, is limited to five or seven bars, depending on the size, and columns from most of manufacturers have the same limitation.
