Practical uses of ultraviolet
WebFeb 7, 2024 · In spite of all pitfalls, UV–visible spectrophotometer-based technique is the most widely used technique for DNA quantification due to its simplicity in experimentation and analysis of obtained results. Additionally, this technique allows to assess the quality of extracted DNA by measuring the protein and/or RNA contamination in the sample. WebJan 29, 2012 · 1. UV has negative effect on eye lens. Couple of years ago, I've used this UV LED for excitation in a fluorometer. For that project, I've bought industrial protective glasses with UV protection (American Allsafe Co. p/n 19159). Regular commercial sunglasses with UV protection would have probably done the job too.
