UV sterilization
- Thread starter ChemMan
- Start date
I use it for the Chinese powders. It is a wand that I bought off of E-bay for around $25. It emits ultraviolet C rays. UV A&B get through the atmosphere, but UV C is blocked completely. If UV C got through it would kill all life on the land areas. Plant and animal. So it is supposed to kill bacteria on counter tops, sink and toilet areas etc. But it just works on bacteria and virus. If there are any toxic chemicals in these Chinese powders, it would have no effect on that.
it damage only live objects like bacteria which do carry DNR so it does not damage hormone itself.
in fact it is totally same as Gama ray irradiation just gamma goes through almost everything while UV does not

" Ultraviolet light irradiation (UV, from a germicidal lamp) is useful only for sterilization of surfaces and some transparent objects. Many objects that are transparent to visible light absorb UV, glass for example completely absorbs all UV light. UV irradiation is routinely used to sterilize the interiors of biological safety cabinets between uses, but is ineffective in shaded areas, including areas under dirt (which may become polymerized after prolonged irradiation, so that it is very difficult to remove). It also damages some plastics, such as polystyrene foam if exposed for prolonged periods of time."
Well, looks like it wont work on bottled up brew

yes thats totally right, it should be used only in case the oil could be exposed to UV directly...

I've tested UV lamps and filters and they honestly are not very effective. The only way to really sterilize the oils or powders is with heat.
The only way to test and to know for sure is to inoculate a blood plate and soy agar plate, wait two weeks and see what you got. I've done it before and those UV lights are really overrated.
