Flow-cell, Small Volume, 10mm path, Style FFeatures WPIs glass and synthetic quartz cuvettes are ideal for UV VIS NIR absorbance or fluorescence experiments. Synthetic quartz can be used in deep UV applications and is recommended for fluorescent applications, as it does not exhibit background fluorescence. Quartz cuvettes (absorbance, fluorescence and flow) are shipped individually packaged. These economic quartz are ideal for precision measurements because of their high quality materials used
