Automated and flexible multi-parametric surface plasmon resonance system
SPR Navi 210A VASA from BioNavis
SPR Navi 210A VASA is based on the MP-SPR (Multi-Parametric Surface Plasmon Resonance) technology. It offers same unique features as SPR Navi 200 OTSO, but is fully automated. The instrument is equipped with a built-in degasser, automated valves and syringe pumps that automate up to 6 samples. To fully enjoy the MP-SPR the additional set of lasers is recommended.

True Goniometric SPR
Unlike most SPR systems, SPR Navi 210A VASA is a true goniometric SPR. This enables a wide angular scan range (= 40–78°) that produces a complete SPR curve with absolute angle information. The true goniometric SPR configuration confers great advantages as it widens the range of refractive indexes at which you can measure, allowing you to characterize surfaces in gas and/or liquid. It also allows you to check the quality of user-defined surfaces before sample injection, providing you with additional evidences. In other words, the wide angular scan range makes SPR Navi 210A VASA an extremely sensitive and versatile characterization instrument.
Customizable flow cell
SPR Navi 210A VASA comes with dual measurement channels for in-line referencing or duplicate measurements. In addition, the easily accessible flow-cell can be customized for user-specific experiments, thus broadening your experimental capabilities. For instance, BioNavis can provide electrochemical flow cells or flow cells equipped with optical fibers for surface illumination. The flow cell shape can also be customized to tailor the flow dynamics to your needs.
Flexible sensor-slide system
With the SPR Navi 210A VASA system, you can use the innovative sensor-slide holder for easy “drop-in” placement of your sensor-slide into the instrument. It allows users to change surfaces within seconds, making SPR Navi 210A VASA an extremely convenient instrument to work with. The sensor-slide holders can be labeled and used for long-term storage of your custom-modified surfaces. Sensor-slides can be modified outside the instrument, with a great number and combination of layers, prior to the actual analysis. This unique removable sensor system provides additional flexibility. It allows you to combine SPR data with other widely used techniques to provide supporting information, including surface topography, surface wettability, chemical composition, photochemical processes, swelling, adsorption.
Contamination free MP-SPR & open design
The proprietary optical elastomer in the SPR Navi 210A VASA finally does away with the need for messy and potentially contaminating index-matching oil. In addition, SPR Navi 210A VASA open design enables convenient access to the easily removable flow cell, as well as to tubing, pump and injection valve. The result is a contamination-free environment for your measurements as well as an open platform for easy cleaning and customizations. The optional immobilizer, a horizontally oriented stand-alone flow cell, can be used for in-situ functionalization of SPR slides. This further minimizes the risk of cross-contamination and enables minimal sample depositions.
