This is a 5mm path length of cuvette designed with screw cap for sealing purpose. This cuvette has 2 optical path lengths in one single cuvette: 5mm and 10mm, which makes fluorescence measurements possible for each path length.

This cuvette cell is high temperature resistant <1200℃,  and high transmission >83%. The screw cap makes it best for anaerobic applications by preventing sample evaporation. The cuvette has 4 polished windows. Fits all standard fluorometers.

  • Solid and open-top (on request) screw cap styles
  • Protect air-sensitive samples
  • Prevent evaporation and contamination
  • Avoid potential spills and exposure to chemical
