test tube
Narrow glass container
A test tube is a thin glass cylinder, closed at one end, used in laboratories to hold small amounts of liquid for experiments.
The term extends figuratively to laboratory science generally: a test-tube baby is conceived through in vitro fertilization rather than natural means.
