Biological sample container
From Memory Alpha, the free Star Trek reference
A biological sample container was a piece of Starfleet medical equipment, used to contain biological samples for study.
In 2369, after discovering samples of DNA on Ibudan's ship, Doctor Julian Bashir put it into a biological sample container in Deep Space 9's infirmary. The small sample of DNA began to grow inside the container, eventually revealing Ibudan's clone. (DS9: "A Man Alone")
