Read It
The display shows the temperature every second. That's the whole routine.
Six hours in a bag. It still looked fine. It read 31°C.
Above 8°C the proteins start to break down. There's no cloudiness, no smell, no warning. The only thing that changed was the number — and nothing was measuring it.
Every Unit. Fully Documented.
Every MedVault is bench-tested against a calibrated reference before it leaves us — range hold, display accuracy, battery cycle, excursion recovery and carry check.
Why People Switch to MedVault
Not every cold pack holds itself to the same standard. We show you the number in every unit.
Cold Chain Built on
the Pharmacy Standard
Pharmacy cold chain ends at the counter. MedVault is built to carry it the rest of the way — locked to the 2–8°C storage range used by U.S. pharmacies, and showing you the reading every second so a dose that looks fine is never a guess.
