Blood products are classed as medical products in many countries, which is why their manufacture is subject to strict guidelines. This means that a small portion of the blood from donors must be stored for several years after the required serological tests and infection marker screening so that the blood donation can be excluded as a cause in the case of an infection of the blood recipient. 2D coded tubes are the method of choice for these retention samples due to their storage safety, clear identification and space-saving size.

However, the tubes from the SAFE® product line are also suitable for the creation of a research-based biobank on the basis of donor blood.
