Slow Freezing Process

The cord blood sample after processing need to undergo a slow freezing process at a controlled rate until it reaches -90'C before it is transferred to a vapour phase liquid nitrogen tank for long-term storage at -185 to -190'C.


  Controlled Rate Freezer
Processing procedure slow freezing by a rate of 1℃ to 2℃ per min.until -90℃
  • Freezing with Sample Probe to monitor the actual freezing situation
  • Full computer control. In response to th releasing of latent heat, the system will adjust the freezing rate to protect the cells
  • More than 10 samples can be processed at one time, enhances processing efficiency
