Spectrum disposable CellFlo hollow fiber membranes are specially designed for the gentle and
efficient separation of whole cells in microfiltration, bioreactor perfusion and culture harvest
applications. Much like our own circulatory system, CellFlo combines the advantages of tangential
flow microfiltration (0,2 µm and 0,5 µm pores sizes) with larger hollow
fiber flow channels (1 mm ID) to provide gentler efficacious micro-separations
without the risk of cell lysis. Other cell separation technologies have a higher risk of
lysis resulting in ruptured cells and culture harvests contaminated with intracellular
macromolecules. Perfectly suited for continuous cell perfusion and bacterial fermentation,
CellFlo membranes isolate secreted proteins while eliminating spent media containing metabolic
wastes and drawing in fresh nutrient-rich media. Consequently, CellFlo enables cultures to
grow to a higher cell density with higher viability providing as much as a ten-fold increase of
daily production of secreted proteins.
Whether performing a cell perfusion or conducting a simple microfiltration, disposable
CellFlo modules can either be autoclaved or purchased irradiated (irr) for quick sterile
assembly. Spectrum offers disposable CellFlo membrane modules in the full range of MiniKros
and KrosFlo sizes and surface areas for processing volumes ranging from 500 mL
to 1.000 liters. All CellFlo membranes have a 1 mm fiber inner diameter,
available in 0,2 µm and 0,5 µm pore sizes.
