TL;DR
- Charge the shipper 24 to 48 hours before it is used, then monitor it for a minimum of 24 hours before it is cleared to carry anything.
- Every single use gets its own validation certificate, and the unit goes in for professional service every 6 months.
- A dry shipper can pass a visual check and still fail in transit. Vacuum seal degradation and internal damage don't show from the outside, which is the whole reason validation exists rather than inspection.
Dry Shipper Validation: Ensuring Temperature Integrity
Validation Protocol Quick Reference
- Pre-Charge: 24-48 hours before use
- Testing: 24-hour minimum monitoring
- Criteria: Maintain approximately -190°C ±1°C
- Documentation: Certificate for each use
- Maintenance: Professional service every 6 months
Why Validation Matters
A dry shipper may "look fine" but fail during transport without proper validation. Vacuum seal degradation or internal damage causes temperature excursions that compromise embryo viability.
