[labnetwork] Nanostrip Storage Container

[Price, Aimee]

Many years ago (~10) I ordered a couple gallons and had one in use, second in storage.  The second bottle leaked and ate through the "secondary containment" plastic bag that it came in, ran down the back of the cabinet, all over the floor in the back hallway.  This required an EHS Hazmat response team since it was a gallon of pH 0 basically which had etched through the paint on the cabinet shelving, door, etc.  They came in with absorbent that was essentially dust.  Pretty much a bad day in a cleanroom.

That was my last experience with Nanostrip. Since then I've always mixed it.  Our new facility has a piranha bath (heated, circulated, etc.).  We also allow users to mix their own, with all the safety requirements in place of course.

To be fair, my bad experience may have also been with an expired bottle.

Best of luck,
Aimee

Hi Mason.
A few years ago I got rid of the last of our Nano-Strip for the same reason.  The original plastic bottle was degrading and I was worried it was going to leak.
We may have been well past the expiry date though.  No other users have requested Nano-strip since then,  so we mix our piranha as needed.

All,

Has anyone experienced problems with storing nanostrip solution (a stabilized form of piranha)? We recently purchased a gallon of it, the first shipment did not arrive due to "damaged packaging during shipment" the second round did in fact arrive but the bottle itself (which is just a plastic HDPE 4L chemical bottle) appears to be degrading, chemical label is completely gone and the plastic lining is - is this something that can be stored in a glass container?  It seems interesting that something specifically engineered and used for dissolving organics and removing polymers is stored in a plastic container.

Thanks,
