You’re looking at a high-flux polyethersulfone membrane here, and the effective surface area options run from 1.4m² up to 2.0m², so you can match it to your patient’s needs or clinic protocol. The smooth inner surface is a real advantage—it cuts down on heparin requirements during the run, which most buyers don’t think about until they’ve seen the difference in anticoagulation management. It’s not suited for low-flux application, obviously, so if you’re running standard bicarbonate dialysis with low flow rates, this isn’t your dialyzer.
Maximum TMP sits at 500mmHg, which gives you decent headroom for high-volume treatments or when you need to pull fluid aggressively. Clearance data we’ve seen puts small-molecule removal like urea at around 190-200 ml/min depending on blood flow, and beta-2 microglobulin clearance is better than with standard polysulfone membranes—roughly 60-70% reduction per session. The blood chamber volume is optimized, but we don’t have the exact priming volume off the top of my head; it’s under 90ml for the 1.6m² version typically.
Gamma sterilization is what we use, and shelf life is three years from the date of manufacture—so you’ve got plenty of buffer for inventory management. Each unit comes in a sterile PE bag, and we pack 24 per carton. The carton dimensions are standard, but check with logistics if you’re shipping overseas because the volumetric weight can surprise you on small orders. Lead time is usually 20 days or so for a standard container, but we can do partial shipments if you’re in a pinch.
We hold ISO 13485 and CE certifcation, and the product meets ISO 8637-2010 standards—so you’re covered for most regulatory submissions in Europe and Asia. Buyers typically ask about the membrane’s fouling resistance under high-flux conditions; we’ve seen consistent performance across 4-hour sessions without significant drop in ultrafiltration rate. It’s basically a workhorse dialyzer for chronic patients, not a specialty unit for critical care.
Bulk pricing depends on volume, obviously—MOQ is usually 500 units for a first order, but we can negotiate down to 250 if you’re running a trial. The 1.8m² surface area is what most buyers go with for standard adult treatments; it’s a sweet spot between clearance and ease of handling. We don’t have the exact molecular weight cutoff on hand, but it’s in the 30-40 kDa range, which is typical for high-flux PES.
One thing we’ve learned from handling these is that teh gamma sterilization doesn’t degrade the membrane structure, unlike some ethylene oxide-sterilized dialyzers that show altered permeability over time. The COA we provide covers endotoxin levels and clearance data from the batch, but we don’t routinely test every unit—just representative samples per lot. Trust comes down to consistency, and we’ve been shiping these for about six years without a major complaint.
We offer four options: 1.4m², 1.6m², 1.8m², and 2.0m². You can pick the one that best fits your patient's needs.
Our standard MOQ is 1 carton, which contains 24 units. For larger orders, we can discuss volume discounts.
Yes, we can supply biocompatibility documentation along with CE and ISO 13485 certificates. Just let us know what specific documents you need.
It's sterilized using gamma radiation and packaged in a sterile PE bag. The shelf life is 3 years from the date of sterilization.
The maximum transmembrane pressure is 500 mmHg. It's designed for high-flux applications, so it handles typical dialysis pressures well.
