Description

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 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.

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, which is derived from Snell’s law and this equation is called Hand’s Law. In this application this is called label-free spectroscopy.

Features
