Phase 22 Rigid Panel

About This Product

Phase 22 is an amazing product for safely shipping animals. Phase 22 changes states (from liquid to solid, or solid to liquid) at 72F. This unique property helps reduce temperature changes in a box. Since Phase 22 material changes states at 72F, it will hold the internal temperatures in packages closer to 72F than without Phase 22. This allows us to safely ship animals in more extreme weather conditions. Phase 22 is completely reusable.

In warm weather: You'll want the phase 22 to be solid when shipped. Simply cool it down below 72F, and it'll turn solid and opaque. The Phase 22 should be placed between the gel and ice packs.
In cold weather: You'll want the phase 22 to be liquid when shipped. Soak the phase 22 in warm water, and it will turn liquid (and clear). Place the phase 22 between the warm gel and heat pack. Panel is 5" X 5" X 1"

This puppy really works a great deal better than plain ol' gel packs. It works better because it actually starts to melt around 71 degrees in contrast to regular water-based gels, which start to melt around 33 degrees Fahrenheit. I use these each and every time I ship my precious frogs---because they're worth it (and so is a live delivery!)

Work like a charm. I've shipped Terribilis, which as quite heat sensitive to Arizona where it was 95 degrees during the day. They arrived just fine and the temp inside the box was 73 degrees. I use these to ship any frogs in any temperatures, they help me feel better knowing that temps will be just right no matter what kind of conditions I'm shipping in.

Phase 22 panels

I don't ship without these things. As the description states, the internal box temps upon arrival are always the listed 68-75 degree mark unless there's an extreme unexpected weather change overnight. They're pretty expensive, but definitely do their job.

Great Product

These work very well! They do everything they say they do. I spent the extra few dollars on the ridged version vs the packets because I'm scared of puncturing them
