: Everything you need to pack your own analytical HPLC columns is included: pump, 20 ml reservoir, column hardware (150×4.6 mm, 316 stainless steel tubing with end-fittings, frits, nuts, and ferrules for two complete, empty columns), and system control software (computer not included). Detailed packing instructions and a DVD are also included. The packing pump is electric, so no pressurized air is required.
