High Flux 1.8h Polysulfone Hollow Fiber Hemodialysis Dialyzer for Renal Failure Treatment

We've been running these through the usual battery of tests—HPLC for residual monomers, pressure decay for fiber integrity—and the batch-to-batch consistency has been tight, roughly within 2% on clearance rates for urea and creatinine across the last ten. The 1.8-hour label refers to the expected treatment time at standard blood flow rates, not any product property per se, and the membrane inner diameter is 200μm with a 35μm wall thickness, which basically determines how well middle molecules like beta-2 microglobulin get pulled out.

Adult patients are the main group, but we have some centers using the 1.2m² surface area version for pediatric cases, and the gamma sterilization means it's ready to go straight out of the box—no extra prep needed. It's better than some lower-flux designs for removing larger toxins, though it's not suited for patients with severe heparin allergies or those on certain anticoagulant protocols where the higher flux might cause excessive fluid shifts.

The CE mark is current, and our company provide a COA with each batch showing endotoxin levels below 0.03 EU/mL and fiber bundle volume within spec—usually 85-95 mL depending on the surface area you order. One thing buyers don't always ask: we retain a sealed sample form every production lot for 18 months, so if there's ever a question, we can pull it for retesting.

Lead time is typically 20 days or so from order confirmation, but if you need a specific surface area like 1.4m² or 1.6m², we usually have stock, though confirm lead time for 1.8m² as it moves faster. Teh MOQ is 500 units for a standdard order, but our company can do smaller trial quantities at a slightly higher per-unit cost.

Also, the potting compound is polyurethane, and we've had no issues with biocompatibility in the last three years of production—it's one of those details that matters if you're running a tight validation protocol. The housing is transparent polycarbonate, so you can actually see the blood flow during treatment, which some clinicians find useful for spotting air bubbles.
