The CoreTainer® is designed specifically for stereotactic core needle breast biopsy samples. It minimizes the need to handle delicate core samples more than once and provides superb image quality. Five individual compartments, each with a radiolucent number, make it easy to identify and communicate the location of cores with calcifications from the specimen radiograph. A watertight lid accommodates formalin and is safe for transporting specimens to pathology. CoreTainer is a one-step system that can save time, improve interdepartmental communication and help maintain tissue integrity of fragile core biopsy specimens.
