This cuvette is designed with 4 clear windows for use in fluorescence applications. This cuvette has 2 optical path lengths in one single cuvette: 5mm and 10mm, which makes fluorescence measurements possible for each path length.

The fused quartz material has a higher transmission of 83% (HTR) or 80% (CRF). This fluorescence cuvette is usable in UV and visible wavelength range. 5mm standard path length and 12.5 x 7.5 mm outer size make the cuvette suitable for most fluorometers.

  • Four Clear Windows for Fluorescence Spectroscopy
  • Dual Optical Path Length of 5 mm and 10 mm
  • PTFE Lid Included with Each Cuvette
  • Fabricated from UV-vis Fused Quartz (190 nm – 2500 nm)
  • Door to Door Shipping Duty Unpaid (DDU) Worldwide
Fluorescence Cuvette Size 5mm

This cuvette has a 12.5 x 7.5 x 45mm outer dimension and a volume of 1.75 mL. The cuvette is designed with PTFE Lid for better chemical resistance (screw cap and PTFE stopper types are better in sealing) applications.  This cuvette is our bestselling fluorometer cuvette.

*HTR: High-Temperature Resistant. Highest quality for advanced experiments. This type of cuvettes are melt and manufactured as one piece, with extraordinary resistance to high temperature (<1200℃) and corrosive chemicals. Transmission is 83% over. Zero data reading variation is available on request (default <0.3%) for 2 or more pieces.

  • Note: These HTR cuvettes can be used with most popular organic solvents, as well as acids and bases. They are compatible with chemicals such as acetone, butanone, DMF, and concentrated hydrochloric acid.

*CRF: Chemical Resistant Fused. Bestseller! This type of cuvettes is resistant to most organic solvents, acids, and bases. However, it has a chance to be stained by some chemicals to the bonding edges. It’s a cheaper alternative to the HTR type.

  • Note: please don’t use the CRF cuvette to store chemicals for a long time. Clean it after use.

*NRC: Non-Resistant To Chemicals. This type of cuvette is assembled with glue.

  • Note: Please note that these NRC cuvettes should not be used with benzene, toluene, aqua regia, ethanol, corrosive solutions, or other similar substances, as they may degrade the bonds between the pieces and cause the cuvette to leak. DO NOT rinse the cuvette with ethanol or similar solutions for cleaning.
