Colorado research & biotech context
Colorado's research base centres on CU Anschutz in Aurora and CU Boulder. Denver has CU Anschutz Medical Campus (Aurora); Boulder has CU Boulder. Labs at these institutions typically buy through institutional suppliers; independent and small-company researchers in Mountain West are the buyers this guide is for.
Denver sees about 13 days a year at 95°F or hotter, mostly in July. Lyophilized vials ride through a hot transit day well; the risk is a box left in direct sun for hours after delivery.
Denver
Expect about 26 nights a year at 10°F or colder (10-year low -34°F). Dry powder is fine frozen, but bacteriostatic water can freeze and crack its vial, and a frozen vial opened straight away pulls condensation onto the cake. Let sealed vials sit at room temperature for 20–30 minutes before opening.
Climate: ERA5 reanalysis via Open-Meteo, daily 2 m temperature, 2016–2025.
