Capillary electrophoresis tubing

Precision tubing for performance

Capillary electrophoresis (CE) tubing is precision manufactured narrow-bore fused silica, with specific treatments available to separate both large and small molecules.

Features and benefits

  • Manufactured from precision bore tubing.
  • Hydrophobic and hydrophilic surface treatments enabling use with proteins, peptides and enzymes.
  • Wide pH range.
  • Column-to-column reproducibility.

Recommended applications

  • Capillary electrophoresis (CE) electrokinetic separation methods including capillary zone electrophoresis (CZE), capillary gel electrophoresis (CGE), capillary isoelectric focusing (CIEF), capillary isotachophoresis and micellar electrokinetic chromatography (MEKC).
  • Capillary electrophoresis mass spectrometry (CE-MS) and capillary electrophoresis surface enhanced raman spectroscopy (CE-SERS).
  • Drug analysis and development.
  • Protein characterization.
  • Forensic analysis.
  • DNA sequencing.

Product specifications

  • 30 µm, 50 µm, 75 µm and 100 µm ID.
  • Untreated, ES2 treatment or ES20 treatment.
