Polyethersulfone dialyzer OCI-HD13M

polycarbonatehollow-fiberhigh-flux

Intended use
Treatment of acute or chronic renal failure by extracorporeal hemodialysis to remove metabolic waste (urea, creatinine), β2-microglobulin, phosphate and excess fluid.

Key features

• Polyethersulfone (PES) hollow-fiber membrane designed for high-flux clearance of small, middle and large molecules
• Good biocompatibility
• Continuous toxin clearance capacity with low albumin loss
• Housing and potting materials engineered for secure assembly and safe use
• Available in multiple surface areas and chamber volumes to match clinical prescriptions
