Abstract: Adsorptive bed devices include a scaffold in housing having a stress absorbing rigid structure and open cells filled with adsorptive beads. The scaffold restricts movement of the plurality of adsorptive beads, absorbs stress induced by a hydraulic pressure gradient along a direction of liquid flow and transfers a portion of the induced compressive stress to the housing. In one embodiment the adsorptive bed is packed into a chromatography column, and in another embodiment the adsorptive bed is sealed in a monolithic block. In another embodiment, the adsorptive bed device includes an adsorptive block, first and second planar distributors and peripheral seal. The adsorptive media includes multiple layers of planarly cohesive media and when operated in a shallow bed configuration possesses significant tensile strength along its planar dimensions enabling it to support the hydraulic pressures that will be generated by the fluids being processed through the adsorptive devices.
