 -Free Wedges- Packaging + Mailing

I've searched a bit on this, and the best
solution I could find was to use little
zip bags.
Any tips? I don't know the first thing
about where my little 2in bags came
from or how they were handled.
As far as I'm aware, some things can take
up to two weeks by USPS - that's quite a
window of opportunity for contamination.
Test tubes are another option I guess.
I've got like 70+ just sitting in a box.

I was under the impression that a fresh agar plate was the polite manner to send them.

Yes, well that would indeed be polite.
Do you mean a wedge transferred to a new
blank plate, just for absolute clarity?
Certainly you must, nevermind I even asked.
All of my work is done with glass, including
petri dishes. Sending out one of those free
is hardly going to occur, so I've got to
improvise.
What about my test-tube idea?
I'd cut out a piece so it would fit nice
and snug, then stuff a sterile cotton wad
in the neck and seal it over with foil.
Then tape around the edge of the foil where
it meets the glass.

If zip bags are the way your leaning I was reading just yesterday how several here seal in a zip bag and ship that inside a CD case for protection.
Microcentrifuge tubes are also apparently in use and cheaper than plastic petris.
Microtubes and baggies could both be sterilized under a germicidal UV lamp.

I like the idea of microcentrifuge tubes.
As for cleaning them though, I would lean
towards pasturizing at +-200deg F.
Low-grade polyethylene will melt anywhere
between 220 and 240 F. I should have thought
of this before - pasturizing LD-HDPE.

the important thing is to make sure it's in a clean place and it isn't mushed. I actually suspect that a ziploc baggie would be pretty good for cleanliness but it could create an aerobic environment that would perhaps allow contaminants to proliferate.
I would caution against putting glass tubes in the mail though if that's the situation. You could consider getting some plastic tubes for selling and trading of cultures. Vacutainers or microcentrifuge tubes or whatever will likely do.
