Abstract

A chromatographic cassette includes a cassette including a chamber, chromatographic media disposed within the cassette chamber, a distribution network fluidly coupled to the chromatographic media and an inlet port and an outlet port coupled to the distribution network. A hyper-productive chromatography technique includes providing a scalable and stackable chromatographic cassette, loading a sample to be processed, operating the scalable chromatographic cassette having an adsorptive chromatographic bed having a volume greater than 0.5 liter by establishing a flow at a linear velocity greater than 500 cm/hr with a residence time of the loading step of less than one minute.
