Key Products


HiFliQ Ni 300x300Protein Ark offers a range of chromatography columns suitable for protein purification; from empty FliQ FPLC columns (1 ml, 5 ml, 10 ml & 20 ml), pre-packed HiFliQ FPLC columns (1 ml & 5 ml) to batch incubation spin columns and Proteus pre-packed spin column kits. With over 25 years chromatography experience, we have laboratory columns to suit all your protein purification needs.

  • The Proteus FliQ FPLC columns designed for 1 to 20 ml resin volume with simple packing procedure and universal 10-32 UNF threads compatible with all standard chromatography instruments (including GE Healthcare’s AKTA systems).
  • Proteus 1ml and 5 ml HiFliQ FPLC columns are designed for effortless purification of recombinant proteins and antibodies. These columns are pre-packed with exceptional high performance resins eg Heparin, Ni-NTA agarose, Co-NTA agarose, Glutatione Agarose, Protein A Agarose and Protein G Agarose to ensure robust and reliable separation each and every time.


Empty FliQ FPLC Column

FliQ Columns 150x150Protein Ark offers empty 1 ml, 5 ml, 10 ml and 20 ml FPLC chromatography columns at an affordable price. Both ends of the FliQ columns have 10-32 UNF threads which fits all common chromatography instruments such as AKTA.

Pack your own resin into these columns. Separate your proteins using an FPLC, HPLC, low pressure pump or a syringe. Use your own resins or use our own high capacity, high flow rate resins eg Protein A Agarose, Protein G Agarose, Super Ni-NTA, Super Co-NTA and Super Glutathione Agarose resins.


ProteoSEC Size Exclusion AKTA Columns

ProSEC 16x 60 column with AKTA 150x150Protein Ark’s ProteoSEC Size Exclusion Columns (SEC) utilize a high performance rigid resin derived from a co-polymer of Dextran and Agarose. We offer 3 different column sizes: 11/30, 16/60 and 26/60 columns with Superdex™ S75 pg and Superdex™ S200 pg behaviour. Our ‘6-600’ HR acrylic columns have a protein separation range within 6kDa to 600 kDa and the ‘3-70’ HR acrylic columns have a protein separation range within 3kDa to 70kDa. Both these HR acrylic columns are ideal for high definition preparative protein polishing steps using all aqueous buffers, at room temperature and in the cold room. The ProteoSEC 16/60 columns are available in the Classic (non-adjustable end adaptors) and Dynamic (adjustable end adaptors) designs. The ProteoSEC 11/30 and 26/60 columns are only available in the Classic design.


  • High resolution (HR) preparative grade columns with comparable performance to GE Healthcare Superdex™ 200 pg (6-600 HR) and Superdex™ 75 pg (3-70 HR) SEC columns.
  • The 6-600 HR column has a separation range of 6-600 kDa. The 3-70 HR column has a separation range of 3-70 kDa.
  • Each column is certified for Height Equivalent  to a Theoretical Plate (HETP) and peak asymmetry: Theoretical Plate Number: > 10,000 N/m & Peak Asymmetry: 0.7-1.5.
  • Three different column sizes:  11/30, 16/60 & 26/60 available with 3-70 HR resin or 6-600 HR resin.
  • Both High Resolution (HR) resins are co-polymers of dextran and agarose and have a mean particle size of ca. 35 µm (20-50 µm).
  • The 16/60 HR columns are available with non-adjustable end adaptors (classic design) and adjustable end adaptors (dynamic design).
