MSE PRO Standard Fluorescence Cuvettes With Stopper, 20mm Path Length, ES Quartz Glass (190 nm - 2500 nm)

20 mm Quartz Fluorescence Cuvette with Stopper, 7.00 ml, for Fluorescence and UV-Vis Spectroscopy

This 20 mm quartz fluorescence cuvette has 4 polished windows, so excitation light enters one face and emitted light is collected at 90 degrees, as a fluorometer cuvette must. It holds 7.00 ml in a 10 mm wide chamber. The MSE PRO cell is made from ES quartz glass.

With 7 ml per fill, it is set up for fluorescence and UV-Vis absorbance work on the same cell.

The PTFE (Teflon) stopper seals the cell against spills and evaporation, which matters for volatile, precious or hazardous solutions.

ES quartz transmits from the deep UV at 190 nm through the visible range to 2,500 nm in the near infrared. That covers UV work such as nucleic acid readings at 260 nm and protein readings at 280 nm, as well as visible and NIR measurements.

The 20 mm path length gives about 2 times the absorbance of a standard 10 mm cell for the same sample, which helps when measuring dilute or weakly absorbing solutions.

Outer dimensions are 45 x 12.5 x 22.5 mm (H x W x D). Check that your spectrophotometer's cell holder accepts this footprint before ordering.

The cell is made by temperature fusion. Other sizes and custom inside widths are available on request.
