What is the function for test tubes?

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 is the function of test tube rack in laboratory?

Test tube racks are laboratory equipment used to hold upright multiple test tubes at the same time. They are most commonly used when various different solutions are needed to work with simultaneously, for safety reasons, for safe storage of test tubes, and to ease the transport of multiple tubes.

What are the three main function of test tube?

Test tubes are widely used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents.

How do you use a test tube?

Hold the test tube at an angle. Point the test tube away from yourself and all other people. Heat the test tube gently from the top of the substance being heated, and always wear safety googles.

How many types of test tube are there?

There are several material types of test tubes: glass, plastic, metal and ceramic. Glass and plastic are the most common while metal and ceramic are less common. There are several sub-types of glass and plastic test tubes.

What is the volume of a test tube?

Test tubes

Can test tube be heated?

It is important to heat the tube gently and uniformly. Use a medium blue flame and move the test tube around in the flame to heat the entire surface of the tube as evenly as possible. This is important to minimize bumping and cracking. Move the test tube in and out of the flame to allow time for heat transfer.

What are the different types of test tubes?

Material Types. There are several material types of test tubes: glass, plastic, metal and ceramic. Glass and plastic are the most common while metal and ceramic are less common. There are several sub-types of glass and plastic test tubes.

What is the function beaker?

Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.

What is a tube rack used for in a lab?

Test Tube Rack. Test tube racks are laboratory equipment used to hold upright multiple test tubes at the same time. They are most commonly used when various different solutions are needed to work with simultaneously, for safety reasons, for safe storage of test tubes, and to ease the transport of multiple tubes.

What is the purpose of a test tube?

Test tubes are used by chemists in the lab to heat, hold and mix small quantities of liquid or solid chemicals during experiments. They have a round bottom and are made of borosilicate glass to withstand temperature changes and resist the reaction of chemicals. Test tubes have clear glass to allow monitoring…

What are cube racks used for in microbiology?

These racks can not only be used for test tubes, but it can also be used to hold culture tubes, centrifuge tubes, and micro-centrifuge tubes. The interlocking cube racks can also be put in the autoclave, as well as ease the transport of multiple different sized tubes.
