What it is and how it's used

The first well temperature and the speed from LN₂ into it decide most warming failures.

Typical failure modes

  • Survival drop across embryos of many freezing dates → warming side.
  • Partial lysis; failure to re-expand.

What to check first

  1. Probe temperature of thawing solution in the well before every session.
  2. Speed and handling; timings per step; media lot.
  3. Post-warm culture conditions and time before assessment.

IFU and practice notes

Follow the kit IFU; record operator and outcome for every warming.

Neutral, and the IFU wins
