Hemodialysis Consumables · High-Flux
High-Flux Hollow Fiber Dialyzer
A polysulfone hollow fiber dialyzer for high-flux hemodialysis in chronic kidney failure, with a membrane structure tuned for middle- and large-molecule clearance. Pairs with our blood line sets for a complete extracorporeal circuit.

Product Overview
The dialyzer is where dialysis actually happens: blood and dialysate flow on opposite sides of a semi-permeable membrane, and everything else in the circuit exists to serve that exchange.
This high-flux series uses polysulfone hollow fibers with a dense inner-layer structure — the selective skin that separates the blood and dialysate compartments. The fiber bundle geometry is optimized so that, at clinical blood and dialysate flows, the membrane clears middle and larger uremic molecules alongside small solutes, supporting high-flux treatment for chronic renal failure patients.
Fiber control technology gives the product a defined sieving coefficient distribution — meaning the membrane's permeability profile is a controlled manufacturing outcome, not a batch-to-batch variable. Specific sieving values are stated in the product Instructions for Use.
The series is offered in two effective areas: HF15 for standard adult sessions and HF18 where a larger membrane surface supports higher clearance targets. Larger sizes in the same platform are available for programmes that need them — see the series lineup below.
Four Design Decisions Behind the Membrane
Built for High-Flux Therapy
A high-flux hollow fiber dialyzer intended for hemodialysis treatment of chronic renal failure patients — the mainstream modality in most maintenance programs.
Middle & Large Molecule Clearance
An optimized hollow-fiber membrane structure assists the clearance of middle and larger uremic molecules, the clinically limiting fraction in long-term dialysis.
Defined Sieving Coefficient Profile
Fiber control technology produces a specific sieving coefficient distribution, so membrane permeability is a controlled, repeatable property. Exact values per the IFU.
Dense Inner-Layer Structure
The polysulfone fiber carries a dense inner layer — the selective barrier that defines solute separation while the open support structure maintains flow.
Supply at tender scale. Manufactured by a maker of dialyzers with two specialized production bases and stable capacity at the level of tens of millions of units per year — volume is not the constraint; documentation and lead time are managed per order.
