Flow Rate Comparison

Flow rate comparison for yeast enzyme separation.

Left, 1 ml/min; right, 5 ml/min. Separation on UNO® Q1 column in 20 mM Tris buffer, pH 8.2, with a gradient of 0–1 M NaCl in 20 ml.

UNO monolith ion exchange columns contain a patented* continuous-bed matrix, allowing biomolecule separations at high flow rates without sacrificing resolution or capacity. In continuous-bed technology, advanced monomers and ionomers are polymerized directly in the column and aggregate into a dense homogeneous network of nodules. The resulting rigid matrix contains interconnecting channels large enough to allow fast hydrodynamic flow at low backpressures. The continuous-bed matrix yields a column with exceptional resolution, speed, capacity, and value for the separation of biomolecules. The homogeneous, nonporous continuous-bed matrix allows extremely fast mass transfer of proteins and eluent to the ionic functional groups.

The UNO S columns are for strong cation exchange. Choose from the following UNO columns:

  • UNO glass columns — provide high-resolution separation of biomolecules. The transparent glass tube allows easy bed inspection and column troubleshooting. Three column sizes provide flexibility for purification protocols
  • UNO replacement columns — provide a simple bed replacement as an alternative to purchasing a new column; two column sizes are available

* U.S. patent 6,423,666.
