Cuvettes are a type of vessel necessary for the precise spectral analysis of liquid samples. Generally used in spectroscopy, cuvettes are designed to hold liquid substances during chemical analysis. These instruments have two or four optical clear windows to ensure you can use light waves to measure the substance of interest without interference from the cuvette itself. They are often used with spectrometers, which measure how much a liquid sample absorbs or transmits a specific wavelength of light.
- In case the sample needs incubation at a high temperature, care must be taken to avoid temperatures too hot for the cuvette.
- So much has changed during this unprecedented time, except your ability to count on Avantor.
- A blank reference measurement provides highly reliable results but for the purpose cell pair with optically matched windows should be used to prevent any absorbance mismatches.
- Like a test tube, a cuvette may be open to the atmosphere on top or have a cap to seal it shut.
Absorbance or transmission determinations shine spectrometer light directly through the cuvette to measure the amount of light absorbed or transmitted through the sample. In this measurement configuration, the opposite-side cuvette walls must be optically "clear" to let light pass unimpeded through the sample. The other two sides of the cuvette volume of a cuvette are often "frosted" to allow handling of the cell without dirtying the optical surfaces of the other two "measurement" sides of the cuvette. These are known as "two sides clear" or absorbance cuvettes. When youpurchase cuvettes for spectroscopy, you will find a diverse selection of premium-quality options.

Please select from the drop down menus and assure the part number's last digit corresponds to the desired pathlength. For example, part number 1-G-10 corresponds to a 10mm pathlength for a Type 1 Glass Cell. REFLEX Analytical welcomes your contact if assistance is required.

Vwr® Spectrosil Spectrophotometer Cells
If solution is transferred into a cuvette using a Pasteur pipette containing air, bubbles may form inside the cuvette, reducing the purity of a solution and scattering light beams. The solution contained in the cuvette should be high enough to be in the path of the light source. In case the sample needs incubation at a high temperature, care must be taken to avoid temperatures too hot for the cuvette. The new ZS Xplorer software will help you determine the appropriate temperature limits and measurement types based on the specific cell selection as highlighted in red below.
