Arizona research & biotech context
Arizona's research base centres on TGen and ASU in metro Phoenix, Mayo Clinic in Scottsdale and the University of Arizona in Tucson. Scottsdale has Mayo Clinic Arizona; Phoenix has TGen (Translational Genomics Research Institute); Tucson has University of Arizona. Labs at these institutions typically buy through institutional suppliers; independent and small-company researchers in Southwest are the buyers this guide is for.
Scottsdale averages 100 days a year at 100°F or hotter. A sealed box on a sunny porch or in a metal mailbox runs well above air temperature, so plan deliveries for when someone is home or ship to a staffed address.
Tucson
Freezes are occasional (5.2 nights a year at 32°F or below), so cold matters only for a box left out overnight in January.
Climate: ERA5 reanalysis via Open-Meteo, daily 2 m temperature, 2016–2025.
