Ideal for cold sterilization, sample clarification or point-of-use filtration,
Spectrum's Hollow Fiber Microfilters are ingeniously designed with
looped DynaFibre® membrane (0.2 µm mixed cellulose ester hollow
fiber) in a small filter device to maximize surface area (SA) and flow rate
while minimizing membrane plugging and protein-binding (< 2µg/cm2).
This efficiency is only possible with hollow fiber devices because the filtration
occurs from outside the porous fibers into the multiple lumen
that pass to the common outlet. Spectrum also incorporates a hydrophobic
vent fiber in the microfilters (except DynaGard®) that readily
passes air bubbles to avoid "air lock", a problem that commonly blocks
the flow in other filter devices. Spectrum offers 5 Hollow Fiber Microfiltration devices:
MiniKap®, MediaKap®, MediaKap Plus, CultureGard®
and DynaGard.
