Tulsa climate & vial handling
Heat and freeze exposure. July highs average 92°F and January lows 29°F, with a 2016–2025 range of -16°F to 105°F.
Tulsa sees about 21 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.
Tulsa averages 54 freezing nights a year. Bring the box inside promptly and let cold vials warm, still sealed, before you open or reconstitute them.
Keep sealed bacteriostatic water (for example Hospira's 0.9% benzyl alcohol vials) out of a hot car or garage; once a vial is mixed with it, refrigerate.
Climate: ERA5 reanalysis via Open-Meteo archive API, daily 2 m temperature, 2016-01-01 to 2025-12-31. Hottest month July, coldest January.
Tulsa research context
Tulsa has no major peptide research institution of its own; most Oklahoma work runs through the OU Health Sciences Center and the Oklahoma Medical Research Foundation. 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 Tulsa's weather.
Heat and freeze exposure: July highs average 92°F and January lows 29°F, with a 2016–2025 range of -16°F to 105°F. Cold-chain packaging is not needed for dry lyophilized vials, but timing delivery to avoid a porch or mailbox at the extremes is.
