High Flux Single-use Dialyzers

Our asymmetric membrane structure provides a unique barrier that adsorbs endotoxins. Other advances in fiber and dialyzer technology enable more disruptive flow to improve solute removal. The resulting steeper sieving curve enhances small and middle molecule clearance without increasing albumin loss.

Optiflux high flux ebeam-sterilized dialyzers feature the improved convenience for use in the arterial end upright or arterial inverted position.
