HyperShear HPLC Mixers

HyperShear HPLC Mixers

  • Static or Dynamic Mixers with highly efficient vortex sheer mixing

  • Reduce baseline noise, increase sensitivity, and improve gradient accuracy

  • Mixing volume optimization is easy with interchangeable mixer cartridges

  • High pressure mixers tested to 15,000 psi.

  • Available in stainless steel or biocompatible PEEK

  • Ideal for microbore HPLC and LC/MS

  • Compact design is easily integrated into any HPLC system

  • In-line, binary, and ternary formats

ASI manufactures a wide range of Mixers to meet the most demanding HPLC mixing problems.  All ASI Mixers incorporate a highly efficient cross-flow shearing mechanism which produces vortex sheer mixing over a wide flow range.  This mixing technology typically delivers between 25 to 200% better mixing efficiency compared to conventional stir bar or tortuous path mixers.  HyperShear HPLC Mixers are available in both static and dynamic formats with volumes ranging from 0.5µl to 1.5ml. Most misers are available in biocompatible PEEK.

Comparison of Baseline Noise

The baseline of the above plot has been enlarged to show the noise levels associated with each mixer. Note the significant reduction in baseline noise with the ASI static mixer.
