azenta.com Storage, Automation & Logistics Sample Warming During Innocent Exposures From an LN2 Freezer: Comparing Temperature, Time & Workflow Using Manual vs. Automated Systems WHITE PAPERStorage, Automation & Logistics | White Paper Azenta Life Sciences 2 Storing samples in liquid nitrogen vapour phase freezers (LN2) is very common and performed throughout the biobanking and cell therapy industries. These freezers are chosen primarily because they maintain a sub -150°C storage environment and thus, keep the samples below -135°C, the glass transition temperature of water (Tg). This cryogenic storage practice preserves sample viability. The concern is what happens to innocent samples (the ones not intended to be thawed) during routine rack exposures. Thousands of innocent s
