SPR imaging system OpenPlex

The compact surface plasmon imaging system with an accessible platform.

  • label-free interaction analysis;
  • multiplexed imaging (up to 400 spots);
  • the choice between 3 different flow cell configurations without concession.

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 3 different flow cell configurations without concession:
1) Normal flow cell for standard surface plasmon resonance imaging experiments;
2) Window flow cell, compatible with fluorescence measurements;
3) Cuvette cell, compatible with electrochemistry measurements.


  • Label-free interaction analysis;
  • Real-time monitoring of kinetic curves;
  • Determination of affinity / kinetic parameters;
  • Multiplexed imaging (up to 400 spots).


OpenPlex Fluidic kit
Includes peristaltic pump, degassing unit, connectors.

SPRi-Continuous Flow MicrospotterTM (SPRi-CFM)
The SPRi-CFM is an automatic printer that uses flow deposition for printing biomolecules. Samples are cycled over the surface and captured from solution, leading to higher biomolecule density, better spot uniformity and improved assay sensitivity.

SPRi-Arrayer is an automatic, compact and portable apparatus. It prints DNA, oligonucleotides, proteins, bacterial clones and other materials with low cross contamination.

Student Kit
The ready-to-use student kit for practical works includes: OpenPlex with external fluidic kit, kinetic kit (ready-to-use solutions and SPRi-Biochips), teaching aid (tutorials).
