BioLab provides an on-orbit biology laboratory that enables scientists to study the effects of microgravity and space radiation on unicellular and multicellular organisms, including bacteria, insects, protists (simple eukaryotic organisms), seeds, and cells.

Biolab support biological research on small plants, small invertebrates, microorganisms, animal cells, and tissue cultures. It includes an incubator equipped with centrifuges in which the preceding experimental subjects can be subjected to controlled levels of accelerations.
