Light sensitive compount storage
I was just cruising about the webernet and I came across thisie here link for <html><a
href="http://www.sisweb.com/lab/wheaton/bottle19.htm">white PE bottles</a></html>
Now some people have had trouble storing reactive and or light sensitive chemicals (eg. Nitric Acid). This kind of thing ought to be much more
satisfactory when compared to brown glass containers, don't you think?

PE = polyethylene, which is susceptible to oxidation - nitric acid is a powerful oxidizing agent. Therefore PE bottles wouldn't be well suited
for storing nitric acid. 
Why not just paint the exterior of the brown bottles in order to further limit the quantity of light that strikes the contents? 
I weep at the sight of flaming acetic anhydride.

All chem boxes from chemi companies are eather glass or PE!
PE has the structure CH3-(CH2)n-CH3 thus oxydation will be very hard at ambiant T!
Alcanes need to be over 300/400°C to start to react with oxydisers...this is far over the melting point of PE!

The best way to have light sensitive chems is to store them in a dark closed box, case the container can be transparent then and exposure to light is
reduced to the moment of use!Most light sensitive chems can stand a little exposition HNO3 is really not a problem!
