Cell lines, certain growth factors, and other temperature-sensitive products require cold chain shipping to maintain quality.
Cold chain standards: Suppliers use validated cold chain shipping methods appropriate for each product:
- Frozen products (-80°C to -20°C): Dry ice shipping in insulated containers
- Refrigerated products (2-8°C): Gel pack systems with temperature monitoring
- Ambient-stable products: Standard shipping

What to expect
Product listings clearly indicate storage temperature and shipping method. Cold chain shipments include:
- Insulated packaging
- Appropriate cooling materials (dry ice or gel packs)
- Temperature indicators showing if temperature was maintained
- Clear handling instructions
Receiving cold chain shipments
- Arrange to receive packages promptly on delivery day
- Inspect temperature indicators immediately
- Transfer frozen items to -80°C/-20°C storage
- Transfer refrigerated items to appropriate cold storage
- Report any temperature excursions to the supplier within 24 hours
Cost considerations: Cold chain shipping costs more than standard shipping due to specialized packaging and express delivery requirements. Costs are shown clearly at checkout before you complete purchase.
