Cold chain 101: keeping pharma and perishables in range

What a validated cold chain looks like, and the questions to ask any provider handling temperature sensitive cargo.

Life Sciences Team 16 Aug 2026 1 min read

A cold chain is only as strong as its weakest handover. The biggest risks are at transfers: airport ramps, customs holds and last mile handoffs.

What good looks like

  • Validated equipment qualified for the temperature range and duration
  • Continuous monitoring with data loggers and real time alerts
  • Preconditioned packaging and defined loading procedures
  • Contingency plans with backup storage and rapid reicing options

Questions to ask your provider

  1. Are your facilities and vehicles audited to the relevant standard?
  2. How are temperature excursions detected and escalated?
  3. What happens if a flight is delayed or a shipment is held at customs?
  4. Can you share the full temperature record after delivery?
