What is test tube in laboratory apparatus?
The test tube is one of the most commonly used pieces of laboratory ware. Test tubes are the perfect shape and size to hold small amounts of substances, usually liquid, which are then manipulated in some way, such as being placed over the flame of a Bunsen burner.
What type of apparatus is test tube?
A test tube, also known as a culture tube or sample tube, is a common piece of laboratory equipment consisting of a finger-like length of clear plastic tubing, open at the top, usually with a rounded U-shaped bottom.

What are the types of test tube?
There are several types of test tube materials: glass, plastic, metal, and ceramic. Glass and plastic are the most common, some are designed to be reused, while others are disposable.
What is test tube?
A test tube is a glass container used in a scientific laboratory. Scientists (and mad scientists) use test tubes to hold chemicals during experiments. If you take a chemistry class, you might use a test tube to handle corrosive chemicals, or to mix two substances safely.
Why is test tube important in laboratory?
Test tubes allow chemists, scientists, and researchers to handle, mix, and experiment with materials safely. The heat- and chemical-resistant nature of the test tube makes it an ideal container for carrying out various experiments. Biologists often use test tubes to collect fluids, culture organisms, and hold samples.
Is test tube a cylinder?
A typical test tube has a rounded bottom, but NMR tubes and certain other test tubes have a flat bottom, so the volume contained in them is a cylinder. You can get a reasonably accurate measure of volume by measuring the internal diameter of the tube and the height of the liquid.
What are the science test tubes called?
Lab tubes are normally found in science labs in their special-purpose racks. Labs use them to store conduct and materials to be used for experiment and research purposes. Tubes are also used for heating, cooling mixing chemicals.
What is the volume of test tube?
The small 13x100mm borosilicate glass test tubes are 100 mm tall x 13 mm with 11 mm inside diameter. Volume is approximately 9 ml. Use with No.
How is glass tube made?
Tubing is formed by blowing air through a blowpipe with a hollow tip and rods are made by using a solid tip on the shaft. The tubing is then drawn over a line of support rollers by a drawing machine situated up to 120m away.
How are test tubes made?
Test tubes made from plastics are formed using injection molding. Injection molding is a process in which plastic is heated and then injected, under pressure, into a test tube mold commonly made from metal.
