The NanoCuvette™ One expands the capabilities of an UV-VIS spectrophotometer to include quantification via refractive index for QC, kinetics and 0.5 µL sample measurements.
The NanoCuvette™ One expands the capabilities of a UV-Vis spectrophotometer to include quantification of non absorbing compounds via refractive index. Use cases include label-free kinetics, label-free concentration determinations, and the possibility to measure on 0.5 μL droplets for low-volume samples. In addition, a free cloud-based online software is available as a lab journal system to analyse spectra, automatically extract results and save information.
It is strongly recommended that each cuvette is only used once, as the product cannot be guaranteed to perform nominally after sample contact. However, the following cleaning protocol has been tested for reusability of the product when used with sugary samples (e.g. undiluted honey).This cleaning manual is provided “as-is” and no warranties are given.
The NanoCuvette™ One is an excellent improvement in workflow for quantitative analysis in numerous industries such as biotechnology, pharmaceuticals, chemistry, foods and industrial applications for quality control.
NanoCuvette ™ One er en fremragende forbedring af arbejdsprocessen ved kvantitativ analyse indenfor adskillige fag såsom bioteknologi, lægemidler, kemi, fødevarer og industriel brug til kvalitetskontrol.

Low volume samples around 0.5 µL can be measured at low cost in a conventional spectrophotometer by dispensing a droplet and flattening it on the optical filter of NanoCuvette™ One. This method enables measurements of relevant static or kinetic parameters at low sample volumes. DI water and sucrose samples are used to demonstrate the method.
The concentration of proteins in solution can be measured by refractive index. In addition to the functionality in SpectroWorks™, ready-to-use Excel spreadsheets for protein concentration from refractive index are provided. These spreadsheets are designed to work with data from NanoCuvette™ One. Thereby, proteins can be quantified label-free using a spectrophotometer without UV absorbance or fluorescence at volumes 0.5 µL or 2 mL.
