Screw Fluorometer Cuvette Size

Fluorometer cells with septa screw caps for use in anaerobic or long-term storage applications. Each cuvette comes with a closed screw cap or an open screw cap with a septa self-healing injection site.

This cuvette is our standard screw cap cell and is a favorite among scientists who perform anaerobic work. The open septa screw cap enables researchers to make sterile injections into the cuvette without compromising the experiment.

These 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.

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.
