test tubes are made of glass and can be used to test chemical reaction of chemicals in small amounts also we can test this reactions by just heating them otherwise we can also use them to store chemicals in small amounts for other tests.
Test tubes are used during many different experiments.
To test compounds and solutions and check if they are basic or acidic or neutral in nature..
a test tube is used for different types of water
To hold test tubes. LOL
Well when you are doing scientific experiments with test tubes you may put different substances or whatever you're using in different tubes therefore to separate them and study them individually... Does that help you at all?
Bigger, fatter test tubes are usually called boiling tubes.
They are called: - Test tubes - Cultural tubes - Sample tubes
it can test experiments if it is successful or failes

A test tube rack is used to hold up test tubes. This is so they do not tip over and spill what is in them.
Glucose studies use gray top tubes. The additive in grey tubes prevent glycolysis. Lactic acid test also uses a gray top.
Test tubes are most often used in professional science and medical experiments to hold samples of substances. They are also frequently seen in school science classes and hospitals.
If the test tubes need to be sterile, you would have to autoclave them.
Test tube stands have a very simple use. They are used to hold test tubes during experiments to prevent them from falling over and spilling.
A test tube holder is a device to ...wait for it...hold test tubes ! ;-) Usually a rack or clamp that keeps them upright (& full if in use).
A group of test tubes are called samples.
85% of 140 test tubes= 85% * 140= 0.85 * 140= 119 test tubes
