NanoCuvette™ S


Particle Size Analysis Using UV-Vis Spectrophotometer

Next-gen Scattering Analysis

The NanoCuvette™ S allows for spectrophotometric quantification of particle/cell size and concentration analysis in numerous industries such as biotechnology, pharmaceuticals, life science, foods, including various industrial applications for quality control.

The capacity of NanoCuvette™ S goes far beyond any product currently on the market in terms of achieving easy, fast, and reliable particle/cell size analysis and concentration determination. With the NanoCuvette™ S you have the functionality to determine small particles down to 50 nm, while simultaneously quantify their concentration.

Expanding Capabilities

The NanoCuvette™ S expands the capabilities of your spectrophotometer and allows you to perform combined angle-resolved light scattering and absorbance at 190-1100 nm. Integrated in the surface is a patented photonic nanocrystal (optical filter), that register light scattering such that it measures particle sizes near the photonic crystal surface.


Why Upgrade to NanoCuvette™ S 

Traditionally, spectrophotometry laboratory work has been limited by lack of robust methods to determine size and concentrations. We upgrade UV-Vis spectrophotometry around the world and across all major instrument brands to create new ways to determine particle size analysis, perfom refractive index measurements in a label-free, fast, cheap, and reliable method.

Technology: How we do it

Absorption versus label-free spectroscopy

With absorption spectroscopy, the Beer–Lambert law relates the attenuation of light to the properties of the material through which the light is traveling:

A = εcl + A0 ,


where A is the absorbance, ε is molar extinction coefficient, c is the concentration, l is the path length and A0 is the background absorbance.

In contrast, when light hits a nanoscale photonic crystal, the resonance wavelength is related to the refractive index or concentration close to the surface:

λ = β(αc + ns) + λ0 ,


where λ is the wavelength, β is a coefficient, α is the specific refractive increment, c is the concentration, ns is the solvent refractive index and λ0 is the reference resonance wavelength. This is called label-free spectroscopy

Lab Work Has Never Been Easier

User Centric Experience

With NanoCuvette™ S particles can be quantified in minutes with enhanced sensitivity, reliability, and reproducibility. It measures concentrations and sizes in a standard spectrophotometer without expensive specialized instrument. Together with the unique user-centric online software SpectroWorks™ it automatically analyses the results in minutes. 

Furthermore, NanoCuvette™ S have the free ”Basic cuvette” spectrum file functionality in SpectroWorks™, which you can use for automatic standard curve processing by using our free report template in our Colab Notebook.


Static Light Scattering and Cloud Computing

Particle can be measured since light scattering depends on angle and wavelength. NanoCuvette™ S utilizes Rayleigh and Mie scattering at any given time to precisely determine the sizes in the dispersion of both large and small particles. SpectroWorks™ use the scattered light to model the size and concentration within the sample using more than 500 million light simulations.
