Freezing cycles
The freezing cycles correspond to the standard set of freezing programs pre-
loaded in the EF600 freezer. Unless otherwise requested, equipment pre-
loaded with a single program (EF600-00 and EF600-01) will run the standard
profile for human embryo cryopreservation (section 6.1). The EF600-10
freezer is loaded with all six profiles below (sections 6.1 to 6.6).
