What is a test tube rack used for?
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 test tube stand and its uses?
Test tube stand or rack is used to hold tubes in upright and aligned position, for easy handling of tubes, and to prevent breakage or spillage. It is an essentialtool in any chemistry or biology lab. ... These stands are durable, heat and chemical resistant.
How do you store test tubes in the lab?
Test tube holders are an easy way to organize test tubes and prevent the test tubes from falling and breaking. These containers also provide a safe way for you to store test tubes, especially when they are being used for on going experiments.
What is the use of test tube brush in laboratory?
Test tube brushes are great for cleaning test tubes and other lab ware including tubing. Constructed of quality bristles mounted on a twisted galvanized wire the brush is tufted at the end for cleaning the bottom of a test tube.
What are the two uses of test tube?
Test tubes are used to hold, mix, and heat chemical experiments. They are used as homes for microorganisms when people want to culture (grow) them. They are also used as collections devices for things like blood samples.
Who invented test tube rack?
Two renowned chemists, Jons Jacob Berzelius (1779–1848) and Michael Faraday (1791–1867), have been suggested as the inventor of the test tube.
How many types of test tube are there?

What is tube brush?
Types of brushes
Brushes are designed for the purpose of cleaning test tubes, therefore are developed to be able to reach all corners of the glassware. ... Similar to radial tip brushes, but more durable and efficient in glassware cleaning.
What is the use of triangular file in laboratory?

Description: Metal file with three cutting edges. Uses: To scratch glass or file.
What is a test tube called?
Centrifuge 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 and closed at the bottom.
What is test tube explain?
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.
What does a test tube measure?
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.
