Activated Carbon for Blood Purification and Hemoperfusion

The most intimate contact with human physiology.

Blood purification places activated carbon in the most intimate contact with human physiology. In hemoperfusion and certain dialysis configurations, the patient's blood flows directly through a carbon bed that adsorbs uremic toxins, drug overdoses, or inflammatory mediators. The material must meet biocompatibility criteria that go far beyond conventional industrial specifications: no endotoxins, no particulate release, no leachable metals, and no activation chemical residues.

The Challenge & PureStar Approach

The Core Challenge: Ultra-purity plus mechanical stability under blood flow.

Blood is a complex fluid with proteins, cells, and clotting factors that interact with any foreign surface. A carbon that releases fines can cause microemboli; one with acidic surface chemistry can trigger complement activation and inflammatory response. The pore structure must capture target toxins without adsorbing essential blood components like albumin.
