What is the easier way to clean quartz uv/vis cuvetts?

30 August 2023 1 8K Report

Is there any esay way to clean quartz uv cuvetts from hard sticked precipitites using availble chemicals in the lab such as acids or basis, not expensive commercial products ?

John Duchek

Do they still let you use cleaning solution? We made that in the lab, I believe from sulfuric acid and sodium dichromate. Nasty stuff, but it removes just about everything given a little time.

On the basic side KOH in alcohol does a good job on many things. Again, nasty stuff and it can etch glass, but not quartz.
