UV light

[ChuCDJK]

I am conducting an experiment on the effects of physical mutagens on
lysogeny vs. the lytic cycle of phages, and I was wondering where I could
get a source of UV radiation (short of setting the petri dishes in the
sun)
I would greatly appreciate any information that anyone might have.

Thank you in advance, 


Sincerely, 

Chenghuan Chu
