Cylindrical lab tubes are used to mix, store, heat, and transport chemicals or samples and can be closed with caps or stoppers to contain the contents. They are shaped to allow quick retrieval of samples inside the tube with minimal loss and are sized to fit in storage racks and other lab equipment.
The standard style, these test tubes have a rounded bottom and are ideal for everyday lab applications. Also known as sample tubes and culture tubes.
