Shipping Frozen Specimens

Plastic/garbage bags
Insulation - (wear gloves!) (https://www.homedepot.com/b/Building-Materials-Insulation-Fiberglass-Insulation/Roll/N-5yc1vZbay7Z1z0utow), silver bubblewrap insulation (https://a.co/d/gmU3NMl) , or packing peanuts
Box - Cardboard is fine, or styrofoam if you really want to be thorough
Dry ice or ice packs - enough to surround your specimen. Dry ice is best. OR ice packs of any kind (I recommend gel ice packs - Like https://a.co/d/9M3f3Ab)
Crumpled newspaper/crumpled brown paper bags

Prior to shipping your specimen, wrap it in two plastic/garbage bags. Squeeze out any air.
Wrap/place ice packs around your bagged & frozen specimen to surround it as much as possible. Freeze contents until ready to ship.
Line whatever box you’re using to ship with a layer or two of some kind of insulation (options listed above). For extra leakage protection, feel free to line the box with a plastic garbage bag before adding insulation.
When specimen & ice packs are frozen, transfer together as a whole into the insulated box. If there’s any loose space in the box, add more insulation or crumpled newspaper to keep everything safe and secure.
Add some insulation on top, and seal the box.
Ship! Regardless of what carrier you choose (I recommend UPS), overnight shipping is best if possible, but 2 day is usually fine in the cold months. If you’re weary, I recommend paying the extra $ for overnight for peace of mind. Make sure we have communicated on arrival date!
I highly recommend shipping on a Monday or a Tuesday, so that there is no chance of the package sitting in a warehouse overnight.
You will be contacted as soon as your specimen has arrived safely.
