Claim 0:
1. A method of thawing a frozen sample in a bag-format vessel, the method comprising:
measuring a plurality of first temperatures of the bag-format vessel in contact with a first surface and a second surface, each first temperature of the plurality of first temperatures measured by a different sensor of a plurality of sensors, each sensor of the plurality of sensors configured to measure temperature at a different location of the bag-format vessel;
comparing each first temperature of the plurality of first temperatures to a first threshold;
determining a subset of the plurality of sensors using the comparison, wherein each sensor of the subset of the plurality of sensors measured a first temperature below the first threshold;
heating the frozen sample using a first heater bank and concurrently heating the frozen sample using a second heater bank;
measuring a plurality of second temperatures of the bag-format vessel, using the subset of the plurality of sensors;
upon a second temperature of the plurality of second temperatures exceeding a second threshold, the second threshold indicating that a partially thawed sample is in the bag-format vessel:
heating the partially thawed sample using the first heater bank, and
terminating heating of the partially thawed sample using the second heater bank; and

terminating the heating of the partially thawed sample using the first heater bank after the partially thawed sample has been heated using the first heater bank for a duration.
