One major goal of biobanks is to provide the best possible biospecimen quality for research use. This can be achieved, notably in accredited structures, by using standardized procedures for collection, processing, and storage of biosamples and associated data. Since tissue samples of a clinical biobank are commonly collected at surgical theaters in satellite locations or hospitals in remote areas, adequate temporary storage of the biosample is mandatory to maintain optimal sample quality. In cases where immediate snap freezing of the collected material is possible, interim storage of the samples in portable dewars filled with liquid nitrogen (LN2) is a widely used method. Therefore, the ideal dewar size and maximum storage time need to be considered to maintain an optimal biospecimen quality. In addition, the nature of the cryotube material is an important aspect for keeping the biosample safe while storing it in LN2. The objective of this study was to test different dewar vessels with respect to LN2 volume and consumption and to analyze the impact of LN2 contact on cryotube material through scanning electron microscopy.
