UV sterilization of PCR reagents

I am setting up a new molecular lab, and will not have access to Type I
water for reagents. I can filter sterilize most of the reagents, and /
or use purchased Type 1 water.
However, I am thinking that small quantities of water that would go
into reagents for DNA stocks (such as TAE for DNA stocks, and water for
dissolving new primers) could be aliquoted into 1.5 mL tubes then
exposed to UV light from a UV lamp (mineralight). Even PCR cocktails
(minus Taq, primers, template and mineral oil) could be UV sterilized
in PCR tubes.
OK, so are PCR tubes and 1.5 mL plastic tubes UV permeable?
If so, which wavelengths of UV are best?
I'd appreciate any advise.
