White Bear Photonics - Standard Cells and Cuvettes

Starna Spectrophotometer Cuvettes are used for holding your liquid samples for absorbance or transmission measurements. The most common are 1-Q-10, 1-G-10 quartz and glass cuvettes, which are considered an industry standard. These cells and cuvettes are designed to fit in every spectrophotometer in the industry. For cuvettes and cells with reduced volume or masked windows, check/verify the Z-height (8.5 or 15 mm) of your spectrophotometer model.
