Storing your baby's Cord Blood
Cordlife uses the U.S. FDA approved cryogenic storage pouch. This multi-compartmentalised cryobag has 20% and 80% compartments. This cryobag also has 2 integrally attached segments which are in compliance with AABB and FACT-Netcord standards. This dual compartment addresses the stem cell expansion programmes in future. That means that when this stem cell expansion technology is commercially viable, you can withdraw 80% of the stem cells for immediate use /treatment while continuing to store the 20% balance for later expansion.
The integral segments also provide the safety and assurance that additional product testing is performed on the associated unit thereby eliminating testing and cord blood unit mix ups. This is to allow for additional testing of the sample should it be required in the future, or for viability testing prior to a transplant. This storage pouch is made of a special material designed specifically to withstand cryogenic temperatures.

Your baby’s cord blood is stored in vacuum insulated cryogenic storage tanks, and are designed to remain at optimal cryogenic temperature of below -150°C for cell storage over long periods.
Cordlife uses MVE Anti-contamination Vapour-phase Liquid Nitrogen Storage System for long-term stem cell cryopreservation.
Vapour-phase storage is preferred over liquid-phase storage as it eliminates the chance of cross contamination between cord blood units as compared with those stored in liquid nitrogen.
The MVE Anti-contamination Vapour-phase Liquid Nitrogen Storage System operates perfectly, even without electrical supply, and is 100% reliable and failsafe with no chance of robotic malfunction. Unlike other storage systems available in the market today, our tanks have never been recalled by the U.S. FDA or the manufacturer.
Over 99% of private cord blood banks also use only vapour-phase freezers. Presently, the majority of stem cell transplantations used cord blood units stored in vapour freezers.
