Casper climate & vial handling

Freeze-exposure market. July highs average 87°F and February lows 14°F, with a 2016–2025 range of -37°F to 100°F.

2 days/yr ≥ 95°F

Heat days are rare in Casper (about 2.3 a year at 95°F+), but the 10-year high reached 100°F, so a heat-wave week is still worth timing around.

162 nights/yr ≤ 32°F

Expect about 28 nights a year at 10°F or colder (10-year low -37°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.

After delivery

Bacteriostatic water such as Hospira's 0.9% benzyl alcohol vials lets you draw a mixed vial more than once; store the sealed water at room temperature and refrigerate after mixing.

Climate: ERA5 reanalysis via Open-Meteo archive API, daily 2 m temperature, 2016-01-01 to 2025-12-31. Hottest month July, coldest February.

Casper research context

Casper has no major peptide research institution of its own; most Wyoming work runs through the University of Wyoming in Laramie. For a lab here, the practical question is less who is nearby and more how a box behaves over 3 days on a UPS truck in Casper's weather.

Freeze-exposure market: July highs average 87°F and February lows 14°F, with a 2016–2025 range of -37°F to 100°F. Cold-chain packaging is not needed for dry lyophilized vials, but timing delivery to avoid a porch or mailbox at the extremes is.
