MP-SPR Navi™ 210A VASA
REQUEST A QUOTE / ENQUIRY FORM
Features
- Automated liquid handling of up to 6 different samples for unattended runs
- Software switch for serial and parallel injections in 2 fluidic channels
- Partial loop injections enabling minimized sample consumption
- Exceptionally wide angular range 40˚ – 78˚ enables measurements of small organic molecules and large proteins but also metallic nanoparticles and cells. One scan encompasses both environments: gas and liquid and enables in-line bulk effect separation providing PureKinetics™
- Two independent wavelength measurements in each fluidic channel, enabling detection of thickness and refractive index or conformation changes
- Optionally the instrument can be equipped with up to 4 different wavelengths measured from each liquid channel for optimal data for layer characterization
- Controlled buffer flow conditions with precise syringe pumps and integrated degasser
- Software package for convenient control of the instrument and easy analysis of the results. 210A VASA comes with MP-SPR Navi™ LayerSolver to determine thickness and RI from multiple wavelength measurements. TraceDrawer™ – a powerful software for determination of affinity and kinetic constants is optional
- MP-SPR Navi™ instruments utilize optical RI matching elastomer and therefore, sensors are very easy to exchange and remove for further analysis with other methods such as AFM or microscopy
- Open design enables convenient access to the easily removable flow cell, as well as to tubing, pump and injection valves
- Complement with electrochemistry, high chemical resistant and gas flow cells as well as fluorescence setup provides combined or validation measurements

Flow-cells
We provide a range of application-specific, user-replaceable flow cells. Standard materials include PDMS, PEEK, and Kalrez, tailored for kinetic or material characterization. Specialized cells combine MP-SPR with electrochemistry, fluorescence, or live-cell studies. All support air/liquid, with a gas cell for pressurized gas.
MP-SPR Navi™ Immobilizer
Our MP-SPR Navi™ Immobilizer is a specialized stand-alone holder for chemical modification and functionalization of sensor surfaces, compatible with MP-SPR Navi™ sensor slides and slide holders.

Additional wavelengths
Simultaneous multi-wavelength SPR measurements, using two to four wavelengths, provide accurate thickness and refractive index data. Three or four wavelengths remove the need for additional assumptions. This technique is vital for material characterization, vesicle analysis, and live cell studies. Navi™ instruments support two wavelengths, while the OTSO, VASA, and NAALI models offer four.
MP-SPR sensor slides
BioNavis provides high-quality MP-SPR sensor slides, compatible with all Navi™ instruments, for precise measurements. Our diverse range caters to various applications. The user-friendly slide holder simplifies ex situ functionalization via spin coating, Lb, self-assembly, CVD, or ALD.
