Freezing cells without liquid nitrogen
VIA Freeze controlled rate freezers are compact electrical systems that do not require liquid nitrogen for freezing cells. Conduction-based cooling enables consistent cryopreservation of cells, including those in umbilical cord blood.
This study used a VIA Freeze system (Fig 1) and specific accessories (Fig 2) to freeze up to four 25 mL cord blood samples in cryobags. Cell work and data collation were performed by UK-based cord blood cell bank, Anthony Nolan.
