Product catalog summary
Overview: The document provides technical details about POLYPURE®, a low flux dialyser developed by Allmed, featuring a proprietary micro-undulated polysulfone membrane. It highlights the manufacturing excellence at Allmed's facility in Germany.
Specifications: The dialyser uses micro-undulated technology to enhance efficiency and clearance by preventing 'bundles' and 'dead-zones' and optimizing blood-membrane-dialysate surface exchange. The membrane's homogeneous pore distribution ensures superior clearances and effective depuration.
Performance Data: The document includes clearance data for urea, creatinine, phosphate, and vitamin B12 at different blood flow rates (QB = 200, 300, 400 ml/min) and surface areas (1.0 to 2.2 m2). The ultrafiltration (UF) coefficient ranges from 8.1 to 16.9 ml/hr*mmHg, with blood priming volumes between 59 and 115 ml.
Materials and Construction: The housing is made of polycarbonate, with polyurethane potting material. The membrane is micro-undulated polysulfone, with an internal diameter of 200 μm and a wall thickness of 40 μm. The device is sterilized through irradiation.
Safety and Standards: The dialyser is designed for safe, bacteria-free, and apyrogenic dialysis. Performance data is measured in vitro according to ISO 8637 standards, using bovine/human blood. The asymmetric membrane provides protection from pyrogens through adsorption and sieving/size exclusion mechanisms.

POLYPURE®-1

POLYPURE® Low Flux Series POLYPURE®–Allmed’s low flux dialyser, using our propriatory micro-undulated polysulfone membrane. Manufactured and developed by Allmed in our world class fibre production facility in northern Germany. Pore distribution: better clearances Allmed Laboratories–Electron Microscopy Image of Allmed membrane The homogeneous distribution of the pores inside the membrane and their constant dimensions allow superior clearances and ideal depuration. OPTIMAL PORE DISTRIBUTION Micro-undulated technology: highest efficacy Micro-undulation technology ensures the highest efficiency and clearances thanks to “bundles” and “dead-zones” prevention together with the optimally increased surface exchange of blood-membrane-dialysate.
