A custom made photochemical reactor using several germicidal tubes and a flow cell in the middle.

Germicidal tubes are filled with mercury vapor and they produce UV-C light with an exact 253.7 nm emission. When the tubes are used, a mercury arc forms behind the fused quartz glass and emits an intense UV radiation that disrupts DNA base pairing and kills bacteria, viruses, and protozoa, it sterilizes quite effectively everything.

If oxygen is present ozone forms in relatively high concentrations under this radiation. The energetic photons from a UV-C lamp could be also used in organic chemistry, just as in this case.

Important to note, that these lamps can cause skin and eye problems, so NEVER-EVER look in them without proper protection.
