What is a Test Tube?
Test Tube Function Types and Diagram briefly discuss below. Test tube common laboratory equipment. It’s call test tube. The test tube consists finger-length cylindrical glass tube made a special type of plastic, with a U-shaped bottom. Purpose of test tube in the laboratory to mix liquid chemicals. Glass or special plastic tubes cannot react with the liquid, so they will not react with the liquid sample or complete the experiment.

Types of Test Tubes
Many types of tube glass used to make laboratory equipment with its own characteristics. These types used in different places in laboratory. The first type of glass is borosilicate glass, which is very high pressure. Quartz glass can withstand very high temperatures. Many parts of quartz glass used in the electromagnetic spectrum to withstand high temperatures.
Similarly, actinic glass can withstand or resist infrared and ultraviolet radiation. The other type hick-walled glass, which can absorb a lot of pressure and used for pressurized applications.
Beakers: These are cylindrical containers with a flat bottom. They have a small mouth for pouring liquid.
Microscope slides: Microscope slides thin flat glass, available in a variety of sizes such as a package of 26 mm (3 x 1 inch) 72 slides per package.
Flask: A flask is a vessel or container used for various purposes.
Petri dish: Petri dish or cell culture dish is a kind of petri dish with a shallow transparent cover, which usually used by biologists to cultivate bacteria, fungi and other cells.
Bottles: Bottles narrow-necked containers used in laboratories, made of common impervious materials of various shapes and sizes. They used to store transport liquids such as ink, water, beer, milk, wine, etc.
Evaporating dish: The evaporating dish used to evaporate the supernatant and solution.
Jar: Jar is a rigid cylindrical or conical container, made of ceramic, glass or plastic, with a wide or open mouth.
Desiccator: Desiccator sealable shell used for desiccator to protect chemicals or moisture-sensitive items, such as cobalt chloride paper.
Test tube:
The test tube is a finger-shaped glass with an open top and a closed bottom.
Drying gun: The drying gun used to remove trace amounts of water or any other volatile impurities in the sample.
Stirring rod: The stirring rod used to mix chemicals and made of solid glass.
Glass distiller: The glass distiller made of glass and metal bulbs with long and curved nozzles for distilling various substances.
Condenser: A condenser is a device that condenses gaseous substances into liquids through a cooling process.
Measuring cylinder: Measuring cylinder used to measure the volume of liquid.
Glass boiling point meter: The boiling point meter designed to accurately measure the boiling point of liquids by measuring temperature.
Volumetric flask: The volumetric flask calibrated to maintain an accurate volume at a specific temperature.
Pipettes: Pipettes used to transport liquids in biological and chemical laboratories and medicine.
Burette: A burette used for analytical chemistry, used to accurately dispense liquid, especially a reagent in titration.
Tube Test Tube Function
As a chemistry student, you must have seen test tubes many times, but you may not know why we use them? What is a test tube?
As mentioned above, the test tube made of glass or plastic. They used in science and scientific laboratories to hold small amounts of liquid for heating and mixing. The most common dimensions are between 50 and 250 mm in length and 13 to 20 mm in width.
Test tubes now widely used in chemical reactions, heating solutions, and growing organisms, such as test tube babies.
1. Used to carry out small-scale chemical reactions.
2. Test tube for biochemical test. The test tube can filled with solid or liquid media.
3. Procedures for the use of test tubes Examples of the use of test tubes in heating materials
4. Clamp the pipe with wooden pliers
5. Heat with a small fire and move the speed control tube back and forth to avoid damaging the reaction tube when heating on coal.
