The Septa Piercing Kit includes the septa piercing 13-mm tube rack (part # 987875) plus the specially designed rack holders that hold the tube in place during septa piercing probe extraction. This rack accomodates the vacutainer 2-3 mL type tubes.

When using the septa piercing capability, you must use a rack with the holder. Additional racks are sold individually for additional storage. The rack holder is interchangeable with other 13-mm tube racks of same part number.
