Plain Neck Glass Test Tube
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom. It is widely used in scientific experiments for holding, mixing, or heating small quantities of solid or liquid chemicals.
Test tubes are available in various lengths and widths, typically ranging from 10 to 20 mm wide and 50 to 200 mm long. The top often features a flared lip to aid in pouring out the contents. Some sources consider the presence of a lip as what distinguishes a test tube from a culture tube. A test tube can have a flat, round, or conical bottom. Some are designed to fit ground glass stoppers or screw caps.
Application:
Test tubes are commonly used by chemists for qualitative experiments and assays. Their design helps minimize mass loss when pouring, makes them easier to clean, and allows for convenient monitoring of the contents. The long, narrow neck slows down the spread of vapors and gases into the environment.
They are also used in biology for handling and culturing live organisms such as bacteria, molds, and plant cuttings. In medicine and forensics, they are used to store blood or other fluid samples. A test tube with a stopper is often used for temporary storage of chemical or biological samples.
Manufacture:
Test tubes for chemistry and physics are usually made of glass, especially borosilicate glass, which offers high resistance to heat and corrosive chemicals. They can be placed directly over a Bunsen burner flame. Culture tubes for biology are often made of clear plastic, such as polystyrene or polypropylene, and are typically disposable after use.
Test tubes may come with pre-filled contents, such as sodium citrate for blood collection. They are highly durable and can withstand temperatures over 300°C.
