Laboratory Temperature Monitoring for Quality & Compliance
Laboratories contain several types of storage units, ranging from -80°C freezers, cold rooms, long-term storage farms, liquid nitrogen dewers, and standard freezer and refrigeration equipment. The CDC's Clinical Laboratory Improvement Amendments and the NIH's Good Clinical Laboratory Practice (GCLP) documents recommend continuous environmental monitoring for laboratory equipment containing samples, research, or drugs.
Laboratories will often utilize refrigeration and freezer units to maintain samples and testing subjects for long durations of time, and as a result, storage conditions need to be properly balanced and maintained for weeks or sometimes months at a time. Therefore, proper preservation of the storage environment is a necessary safeguard for all laboratories, as samples or research materials may be the key to the next significant research development.
Additionally, GCLP best practices highlight the importance of corrective action procedures if excursions do occur in laboratory settings, stating "The lab(s) should also maintain daily (or “dates of use”) record of temperatures and other monitored conditions (e.g. humidity). For observations that fall outside of designated tolerance ranges, the laboratory must maintain appropriate documentation of corrective action for these out-of-range temperatures and other conditions."
