General tissue specimen container IVD, fixative/saline

General tissue specimen containers with fixative or saline are single-use devices designed to preserve and transport tissue samples—such as biopsies—from collection sites to diagnostic labs. They prevent degradation of specimens during handling, ensuring accuracy for in vitro diagnostic testing like histology or pathology analysis.

These containers are typically regulated as in vitro diagnostic (IVD) devices, often classified based on risk and intended use rather than the container itself. They are commonly supplied as standalone units or as part of larger specimen collection kits, adhering to single-use standards to maintain sterility and reliability.
