Due to the consistent flow dynamics between hollow fiber membranes, Spectrum filters lend themselves to
direct volume and surface area scalability by increasing the number of fibers while maintaining the same
fiber flow path length. This allows you to easily transition from R & D
(MicroKros®, MidiKros®, MiniKros® Sampler) to Process Development
(MiniKros) and on to Production (KrosFlo®). Module total length (TL) and fiber effective length (EL) are shown below.
