noun

sequestration

see-kwuh-STRAY-shuhn/ˌsiːkwəˈstreɪʃn/

Isolation from ordinary contact or circulation.

The specimen's sequestration keeps its jar isolated in a separate closed compartment.

One laboratory specimen jar is deliberately separated inside a clear closed compartment while other jars sit together outside; isolation clearly physical, no labels or biohazard symbol.
Etymology

A depositing for safekeeping involved placing something in another’s custody. The associated idea of removal developed into separation, so sequestration names the act of setting something apart.
