They are commonly used in diagnostic testing, sample storage, and various research and laboratory procedures.

Plastic test tubes are lightweight, durable, and resistant to breakage, making them a practical choice for many applications. The smooth interior of the tube allows for easy pouring, mixing, and transferring of liquids or small solid samples. They often feature a rounded bottom for stability when placed on a flat surface.
