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% (CRF-H & HTR & HTR-5) or 80% (NRC & CRF). 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 Lid Included with Each Cuvette
  • Fabricated from UV-vis Fused Quartz (190 nm – 2500 nm)
  • Standard Optical Path Length of 10mm
  • Door to Door Shipping Duty Unpaid (DDU) Worldwide
Quartz Cuvette Sizes Teflon Lid

*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. CRF-H has a higher transmission (83% v.s. 80%) than CRF and the same transmission with HTR.

  • 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.
