This cuvette is designed with 4 clear windows for use in fluorescence applications. The 4 windows allow measurement of the fluorescence at right angles to the beam path.

The fused quartz material has a higher transmission of >83% (higher than normal type 80%). The cuvette is usable in UV and visible wavelength range. 10mm standard path length and 12.5 x 12.5 mm outer size make the cuvette suitable for most fluorometers.

  • Four Clear Windows for Fluorescence Spectroscopy
  • PTFE Stopper Included with Each Cuvette for an Airtight Seal
  • Fabricated from UV-vis Fused Quartz (190 nm – 2500 nm)
  • Standard Optical Path Length of 10mm
  • Door to Door Shipping Duty Unpaid (DDU) Worldwide
1cm Quartz Cuvette Sizes

This cuvette has a 12.5 x 12.5 x 45mm outer dimension and a volume of 3.5 mL. The cuvette is designed with PTFE stopper caps for use in airtight sealing (screw cap type is better in sealing) applications. Each cuvette comes with a closed PTFE stopper cap. The PTFE stopper creates an airtight seal to prevent evaporation and atmospheric contamination of the solutions.

Note: The stopper should be inserted gently into the top of the cuvette; excessive force will cause difficulty with removing the stopper.
