Why Our Quartz Cuvettes?

It’s not necessary to always use quartz cuvettes and it depends on the wavelength range you are targeting. Quartz cuvettes have a high transmission rate (80% or higher) @ UV wavelength range while Optical Glass or Plastic (PS or PMMA) reflect the light.

Exceptional Accuracy

Optical Path Length and Parallelism are Exceptional Accurate.

Chemical Resistance

Very High-Temperature Stability (<1200℃) and Chemical Resistance.

Guaranteed Transmission

Guaranteed 83% From 190nm up to 2500nm of the Quartz Material.

Proven Accuracy

Guaranteed Precision of Pair Difference of 0.3% (0% On Request).
