Caplugs Evergreen offers a wide variety of columns for use in drug extractions, HPLC sample preparation, general chromatography work and applications and other research procedures. Our Surety Columns® and Sera-Separa® series are specifically designed for use in fibrin removal and macro particles from serum to prevent line clogging.
