Designed for gentle cross flow filtration of small volumes ranging from
2 - 50 ml, disposable MicroKros Hollow Fiber Modules are the first efficient
and practical tangential flow filtration device for R&D volumes in
the laboratory setting. While MicroKros modules are typically operated
by a peristaltic pump, these devices also offer the unique advantage
of manual operation for quick and convenient separations for small
volumes. Concentration utilizes two retentate syringes connected to
the luer inlet/outlet ports to pass the sample back and forth through
the membrane lumen while a third syringe collects the filtrate by way
of one of the side-ports. In diafiltration, a fourth syringe can be used
to either supply more sample for concentration or buffer for diafiltration
via the luer T connector.

While MicroKros modules can be operated using a small capacity peristaltic pump, these devices also offer
the unique advantage of hand operation for quick and convenient separations of very small volumes. Hand
operation utilizes two retentate syringes connected to the luer inlet/outlet ports (by way of Luer T's) to pass the
sample back and forth through the membrane lumen. A third syringe is connected to one of the female luer side
ports to receive the filtrate as the retentate volume diminishes. A fourth syringe, connected to one of the inlet Luer
T's can be used to either supply more sample for concentration or buffer for diafiltration.
