Manual label-free molecular interaction analysis machine Flexible Research Platform

Surface Plasmon Resonance imaging made easy

Designed to meet the demands of biologists, biochemists and biophysicists, the OpenPlex is a flexible surface plasmon resonance imaging system.
OpenPlex is your companion for the development of label-free and multiplexed bio-assays and molecule detection. It is a robust and compact system designed for simple use and high versatility. Its open format, dedicated sensor chips and manual operation enable numerous types of experiments to be explored without compromise, covering chemistry, biochemistry, physico-chemistry and biomolecular interactions.

Open your research areas with OpenPlex! Choose between three different flow cell configurations without concession:

  • Normal flow cell for standard surface plasmon resonance imaging experiments
  • Window flow cell, compatible with fluorescence measurements
  • Cuvette cell, compatible with electrochemistry measurements

“We are able to generate consistent results that enable us to identify full binding coefficients for multiple candidate aptamer sequences simultaneously. The instrument […] has become one of the most essential tools that we have.” Dr. G. Penner, NeoVentures Biotechnologies, Canada

“…an essential tool […] for the characterization of sophisticated ultrasensitive diagnostic platforms integrated with either nanomaterials, modified gold nanostructures or microfluidics”
Prof. Maryam Tabrizian, McGill University, Canada

“The accessibility of the hardware and the flexibility of the software […] allow us to stretch the limits of what can be studied with SPRi. We have been able to modify the flow cell to study bacterial cells and biofilms in unique geometries.”
Dr. E. D. Goluch, Northeastern University, USA
