MP-SPR Navi™ 200 OTSO 

Semi-automated and modular

MP-SPR NaviTM 200 OTSO is entry level MP-SPR system making it ideally suited for teaching and educational purposes. Open design is optimal when auxiliary instruments are to be used.

Features and benefits:

  • 4  simultaneous  measurements  in  2  fluidic  channels,  two independent  wavelength  measurements  from  the  same  spot, enabling detection of thickness and refractive index or conformation changes

  • Exceptionally  wide  angular  range 40˚ - 78˚ enables  measurement  of small  organic  molecules,  and  large  proteins,  but  also  metallic nanoparticles and cells. One scan encompasses both environments: gas and liquid and enables to separate bulk effect in line using PureKineticsTM.

  • Controlled liquid flow conditions with peristaltic pump

  • Manual filling of injection loops required

  • Parallel injections into both flow channels

 

  • 200 OTSO is sold with a basic software package of MP-SPR  Navi™ Control and DataViewer for convenient control of the instrument and basic analysis of the results. Advanced analysis modules are optional: MP-SPR Navi™ LayerSolver to determine thickness and RI from multiple wavelength measurements and TraceDrawer for  MP-SPR  Navi™ - powerful  software  for  determination  of affinity and  kinetic constants and more.

  • MP-SPR Navi™ instruments utilize optical RI matching elastomer and therefore, sensors are very easy to exchange and also can be further analyzed 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 valve.

  • Complement the instrument with electrochemistry, high chemical resistant and gas flow cells as well as fluorescence setup to obtain simultaneous validation measurements.

  • The instrument enables attachment of a separate autosampler, pump, degasser or even own microfluidic sample preprocessing cartridge.

 

See how to measure thickness and refractive index of thin inorganic layers using MP-SPR!

Thin metal films from 3.7 Ångströms up to 100 nanometers thick can be measured. Transparent films can be measured up tens of micrometers in thickness. Besides thickness and refractive index, MP-SPR measures also interactions with different gas or liquid samples, including ethanol or toluene vapors, solvents, but also plasma and serum. This allows real-time measurement of antifouling capabilities of thin film coatings as well as measurements of biocompatibility.

Real-time conformation changes can be measured for instance upon change of temperature, pH, electric potential or light trigger. 200 OTSO is a semi-automated MP-SPR instrument with 2-channel fluidics. It can be combined with different techniques including electrochemistry and fluorescence. 200 OTSO can be equipped with up to 4 wavelengths in the same channel, allowing reliable measurement of thickness, refractive index and dispersion coefficient.

200 OTSO is designed and manufactured in Finland. Its name comes from vast Finnish forests and means a bear.
The older generation of this model were SPR Navi™ 200 and KSV SPR 200.
