How long does it take to get the “VT-08” Cool Cube™ ready to hold my vaccine?

The time varies between prep methods:

    • Method A: ≈ 5 hours
    • Method B: ≈ 24 hours
    • Method C: ≈ 3 hours

In the user guide we recommend Method A, although all methods work. Choose the method that works best with your schedule.

If you store the PCM panels in your refrigerator they will be available to use whenever you need them. Shake the panels to see if they are solid. If they are slushy your refrigerator is too warm. If the panels are slushy they will still work, but the hold times will be decreased.

Prep Method A:

  1. Place panels in a freezer until all PCM turns solid (i.e. 2 hrs. @ -15°C). Shake to verify.
  2. Transfer panels into a fridge at least 3 hours before use. Panels may be stored in the fridge until needed for assembly or the PCM melts.*
  3. Before assembly, shake panels to verify PCM is solid. If liquid is heard, restart at step 2a to ensure longest hold time. Using liquid panels, or panels with a solid/liquid combination, decreases hold time.
*If a refrigerator maintains 4°C or below, the PCM within the panels will not melt (melting point is 4.5°C), which will keep the panel solid indefinitely until pack-out. If the refrigerator maintains 5°C or above, periodically check for melting and restart at step 2a to ensure best performance.
