Our SQ40 Blood Transfusion Filter is a 40µm rated screen-type filter designed to protect your patients from potentially harmful microaggregate and non-blood component particulate matter. Filtration is based on direct interception to retain particles and microaggregates, which are comprised of leucocytes, fibrin, and platelets that form during the storage of blood. These range in size from 10 to 160#m and can therefore pass through the 170#m clot screen present in blood administration sets1. Microaggregate filtration is a proven, cost-effective solution for the prevention of blood transfusion-associated complications. Our SQ40 Blood Transfusion Filter is available in multiple configurations to meet your transfusion needs.
