How to filter the UV light higher than 200 nm?

09 September 2019 1 10K Report

We are dealing with a problem, that we need to filter off wavelengths higher than 200 nm which are produced by our VUV ozone generation lamps (T5 4PIN, 80 cm length. 185 + 254 nm). Do you have any suggestion how to make that? We were thinking about some kind of filters like shortpass edge filters, but they lack diameters for us.

Dear Tomas,

use cylindric borosilicate glass.

Which reagent is best among 'Dimethylglyoxime" and "Dithiothreitol" for spectroscopic determination of Nickel ?

What I think is Dithiothreitol. As it is water-soluble and does not form a precipitate. But, the thing is it contains sulphur which is quite hazardous to aquatic animals.
