Abstract
The present invention generally relates to thawing a cryogenically frozen sample. The systems, devices, and methods may be used to heat a sample holder, the sample holder configured to receive a sample container holding the frozen sample. A sample thaw start time may be identified by measuring a temperature of the sample container and/or a temperature of the sample. A sample thaw end time may be calculated as a function of the sample thaw start time. In some embodiments, the same thaw start time may be identified by a significant change in a first derivative of a warming curve of recorded temperature measurements. The sample end time may be calculated by adding a constant to the sample thaw start time. The constant may be the average sample thaw time per the sample container.
