UV sterilization of polystyrene.
    #27619537 - 01/15/22 08:08 AM (2 years, 4 months ago)

so uv should kill pretty much whatever over a certain amount of exposure..
People say it might not work because the UV won't pass through glass or most plastics. But say I opened the plate so it had absolute exposure top, bottom and inside, and placed the UV sterilizing unit in front of my flow hood?

I'm looking at microplates but they're all polystyrene....
And potentially this would work with regular disposable Perris as well..


What happens to spores and bacteria when they die from uv? They're still visible under a microscope right? But I would have to put some blue on them to ensure they died?

i went to staples and got a box-like uv sterilizer on clearance for 25$.  the checkout lady said it was originally 130$.  i have some empty dishes i was intending to test this with, because reusing my dishes would be great.  it's plastic i hate to toss so much of it.
anyways when i eventually get around to doing it, i'll post my results.  the plates were all growing with something.  i thought a good test might be, get the agar out, wipe with windex + microfiber cloth, UV sterilize, swab and then plate the swab.  once i have 10 to reuse i'll test it.

There are some reviews of those on YouTube. At least one ha, comparing several UV products.
