Purpose: Primarily of concern for microbiology or ecotoxicology samples received frozen as the integrity of the analysis is significantly impacted with frozen samples. In some regions, regulation also requires that all samples must not be received at the lab frozen.
Tips:
- Review the amount of ice used for transporting samples to the lab, particularly in cold winter months
- Pack samples with some additional packaging material to act as insulation and prevent freezing
Process: The lab contacts you to confirm how to proceed with the sample.
