  • High throughput for MP-SPR
  • 96 and 384well autosampling
  • KineticTitration for additional speed
  • 4-channel fluidics with serial and parallel injection

The MP-SPR Navi™ 420A ILVES (named after the Finnish lynx) is the ideal solution for high-throughput molecular interaction studies with MP-SPR. Minimal dead volumes in 4-channel fluidics also make it the first choice for studying small molecules.

For this, the ILVES comes standard with two lasers for each channel, which, by the way, can be switched in parallel for high throughput or serially for differentiated analyses. KineticTitration provides additional speed, and the included TraceDrawer software package the appropriate analysis of the collected data.

With PureKinetics™ feature for high quality kinetics, MP-SPR is a powerful and sensitive tool for direct measurements of small molecules.



MP-SPR helps you to measure biomembrane interaction kinetics as well as underlying structural changes.



Whether you develop metal, silica, polymer nanoparticles or work with DNA polyplexes, liposomes, viruses or microvesicles, MP-SPR is an excellent choice for drug delivery studies - from real-time targeting studies to real-time internalization with the same instrument.



MP-SPR enables to move from drug-target measurements, through drug-membrane interactions all the way to drug-cell interactions. Differentiate internalization from permeation in real-time and label-free. Study cell attachment on different coatings.



Antibody-antigen interaction affinity and kinetic measurements can be performed in diverse liquids including complex liquids such as serum or saliva.



Biosensor development


MP-SPR can be combined with electrochemistry to measure catalytic interactions, electroswitching surfaces and also to develop electrochemical biosensors.  

Biosensor Development

From nanoparticle-based competitive assays through electrochemical sensors to direct assays, MP-SPR shows all the steps of your assay may you develop it on top of glass, polymer, silica or metal surfaces! More...

Gas sensor development MP-SPR works also with gas samples - from 2 dalton hydrogen up to vapours. More..


Biomaterials and coatings

Biomaterials MP-SPR measures interactions on polymers up to 5 µm thick, which makes it the most sensitive label-free technique for biomaterial interaction studies and layer characterization. Therefore, MP-SPR also helps with formulations for controlled drug release, novel coatings for cell and tissue engineering as well as industrial coatings.

Unique Multi-Parametric Surface Plasmon Resonance (MP-SPR) instruments can extend applicability of SPR also to clinically relevant complex liquids, such as 100 % serum, plasma, urine, bacteria and cells.


Measurement principle

Real-time and label-free Multi-Parametric Surface Plasmon Resonance (MP-SPR) is based on a true goniometric SPR arrangement with a rotating detector. Exceptionally wide angular range 40-78 ̊ is measured, real angular resolution 0.001 ̊.

Liquid handling  

Automated Liquid handling from 96well plate for unattended runs. Precise syringe pumps and integrated degasser. Flow rate from 1 μl/min up to 1000 μl/min. 4 flow channels, software switch for serial or parallel injection. Dual loop injection mode for KineticTitration functionality.

Sample consumption

Minimum sample loop volume 100 µl, partial loop injection option, minimum injection volume 50µl.. PureSampleTM function.

Wavelength of light

Dual wavelength, 670nm and 785nm in all flow channels.

Refractive index range

1.00-1.40 (measurement bulk environment) which can be extended with additional wavelength
Layers that MP-SPR can measure can have much higher RI such as diamond like carbon (2.7) and inorganic crystals.
MP-SPR determines also complex refractive index of liquids, gases and solid layers.


Measurements can occur in gas and liquids. Liquids can be aqueous solutions or organic liquids such as ethanol and acetonitrile or DMSO. Or complex biological matrices (serum, saliva, cell culture media).

Mode of operation

Angular Scanning mode, or “MP-SPR mode”: scanning across a range of angles providing full SPR curve and multiple parameters. Several sensograms can be distinguished from the full curve, such as PureKineticsTM. Sampling rate depends on selected angular range and resolution, typically less than 2 seconds.

Fixed Angle mode, “traditional SPR mode”: measurement at a single angle, providing time – intensity sensogram. Mode for fast kinetic studies - sampling rate from 1ms

Measurement Range

Thickness from Ångströms to micrometers (true range depends on refractive index of the material). Kinetics: ka = 103 – 108 1/(M*s), kd = 10-7 – 0.1 1/s, KD = 10-3 – 10-12 M


Smallest detected molecule: in gas Hydrogen (2 Da); in liquid small molecules <100 Daltons
