Challenges before implementation
Dr. Fleischmann, Biorepository Manager at Broadband Infrared Diagnostics, faced several challenges in the lab’s thawing process. Handling human plasma, serum, and other biological samples stored at -80℃, the team relied on water baths set to 4℃, which took 1 to 1.5 hours to thaw a full rack of 96 tubes (0.5ml aliquots). Even then, uneven thawing was common—samples on the edges thawed faster, while those in the center remained frozen. This inefficiency slowed down the research process and introduced variability in the sample quality.
