Travel with SS-31: Type Comparison
Domestic flight under 6 hours Insulated lunch cooler + 2 freeze packs + USB data logger 8–12 hours Carry-on only; declare at TSA screening; bring institutional letter Sufficient for short trips if freeze packs are pre-frozen solid; single failure point if pack

- Domestic flight under 6 hours
- Insulated lunch cooler + 2 freeze packs + USB data logger
- 8–12 hours
- Carry-on only; declare at TSA screening; bring institutional letter
- Sufficient for short trips if freeze packs are pre-frozen solid; single failure point if packs thaw early. Budget option but no redundancy.
- Domestic flight 6–24 hours
- Validated medical cooler (Pelican BioThermal, SOFRIGAM) + phase-change materials + data logger
- 48–72 hours
- Carry-on only; declare biologics; documentation required
- Gold standard for peptide transport; validated hold time exceeds trip duration by 2×; reusable across multiple trips. Worth the $150–300 investment for high-value compounds.
- International flight or multi-day conference
- Hard-shell medical cooler + PCMs rated for 96 hours + dual data loggers + backup freeze packs
- 72–96 hours
- Customs declaration required; research protocol letter essential; confirm destination import rules 30 days early
- Maximum redundancy; dual loggers protect against single device failure; extended hold time covers delays and inspections. Mandatory for SS-31 valued at $500+ per vial.
- Ground transport under 4 hours
- FRIO wallet (evaporative cooling) or soft cooler + single freeze pack
- 12–24 hours
- No TSA considerations; verify destination has refrigeration upon arrival
- Minimal but adequate for short lab-to-lab transport; FRIO wallets require activation (soaking) 10 minutes before use; humidity-dependent performance limits reliability in wet climates.
- Emergency backup (missed connection, lost cooler)
- Portable 12V car refrigerator or hotel mini-fridge + thermometer
- Continuous while powered
- Not TSA-compliant for flight; ground transport only
- Last-resort solution if primary cooling fails; requires AC or car power; hotel mini-fridges often cycle between 4–12°C, risking temperature excursions. Monitor with thermometer every 2 hours.
