The Unison Family of columns provide a wide range of high quality reverse phase and normal phase columns. The quality of our material provides high efficiency with low backpressure and 100% aqueous stability. Peak shape is also improved with the use of our polymeric end-capping technology. The Unison series of columns are available with C18, C8, Phenyl, Amino and Silica stationary phases to meet a wide range of chromatographic needs.

  • High efficiency 5µ columns with mono-dispersed packing for low backpressure
  • Unique ligand binding provides no phase collapse in 100% aqueous conditions
  • Tri-functional polymeric end-capping reduces unwanted secondary interactions and gives better lifetime
  • World class reproducibility
  • HT and UP hardware able to operate in pressures up to 1000 bar
  • High efficiency and available shot column dimensions are ideal for high throughput applications
