Sera-Separa and Surety Columns

Caplugs Evergreen Sera-Separa® and Surety® Columns are both ideal for use in removing fibrin and macro particles from serum to prevent line clogging.

  • Surety® Columns have integral caps that fit directly onto most round, conical and standard bottom serum cups
  • Sera-Separa® columns feature a wide-body style that prevents sample probes from hitting side walls and a graduated barrel tells exactly how much liquid has been filtered
  • Sera-Separa® are inserted directly into blood tubes for filtering
