Once your cord blood has been processed, we store the stem cells in tanks holding vapor nitrogen at optimal long-term storage temperatures between -175º C to -190º C. We use vapor nitrogen over liquid nitrogen due to vapor’s ability to remain at a consistent temperature throughout the tank. Additionally, using vapor nitrogen protects the frozen cord blood from any infections or bacteria, which are able to “swim” through liquid nitrogen and infect other cord blood specimens.


Our tank’s temperature is monitored electronically with readings every hour, and we have two levels of back-up alarm systems should the temperature be compromised in any way. If the temperature increases even slightly then the alarm goes off. The alarm is then sent through an automatic calling system to alert our staff, one of whom is on call at all times, who will rectify the situation. The system has a large back up battery and then a backup generator connected to this.

The permanent storage is in the Maze cryogenic facility in Purchase, NY. Our lab is continuously inspected and assessed by the FDA for compliance, and has been FDA approved since 1997.

We do not charge any retrieval fees. No matter where you are, we can ship your cord blood to you.

Cord blood that is already frozen can travel around the world without any loss of viability. There are no fees associated with retrieving your baby’s stored stem cells if they’re needed for a transplant. No matter where you are in the world, if you need your cord blood, we can send it to you.
