NanoCuvette™ One
Basics
Flyer
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.
Product Description
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.
Cleaning Manual
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.

Application notes
Droplets and low volume samples
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.
Enzymes and kinetics
Hexokinase activity can be easily detected label-free in real-time with NanoCuvette™ One.
Protein concentrations and Refractometry
Protein concentration determination is fast and easy with the novel NanoCuvette™ One.
Saliva and starch degradation
NanoCuvette™ One can be used to study the degradation of starch
over time by amylase enzymes from saliva.
Glycerol concentration and QC
Quality control of glycerol in a solution can be done fast and easy with the novel NanoCuvette™ One.
Buffers and QC
NanoCuvette™ One is used to quickly determine the quality of a buffer.
Sugar and Refractometry
Refractive measures are widely used in the sugar industry for rapid quantification of the sugar content in sugar solutions.
Honey and Water Content
NanoCuvette™ One offers a quick and easy way to investigate honey quality and moisture content.
Coffee and Sugar
NanoCuvette™ One offers a quick and easy way of detecting sugar in your coffee.
Apple juice and QC
Refractometry is widely used in the quality control of juice and other beverages.
Technical notes
Protein calculations
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.
