Biomedical Grades

POCO has developed post synthesis modifications to make our graphites more suitable to specific conditions. As a producer of highly technical, specialty materials, POCO also offers design engineering support, precision machining, and material testing. Diverse applications include precision parts, graphite filters for blood dialysis machines, graphite electrodes and heating elements.

 

The compatibility of carbon and graphite with human tissues and bodily fluids have allowed POCO materials to be used in a variety of implants. Applications include artificial heart valves, dental mounts, cancer treatment devices and blood analysis devices.
