Question

What is a fusion tube? Is a fusion tube the same as a test tube?

Answer 1

Hint: Fusion tube is like a boiling test tube but unlike boiling test tube it is thin and small in size. It has a capacity of 95ml and is made up of borosilicate glass. It is used for analysis of elements in a compound by fusing them with another compound.

Complete answer:
-No test tube and fusion tube are different from each other, However fusion tube is smaller than test tube.
-Fusion tube:
Fusion tube is a thin tube which is often used in laboratories such as sodium fusion and knowing the melting and boiling point of substance. We take a small amount of chemical substance in a fusion tube which is heated excessively. It is made up of thin glass because it is intended to be broken in a water container when fusion ends up.
-Test tube:
Test tube is a thin-walled cylindrical shape tube with a flat bottom. Test tube is used in mixing chemical substances, heating and cooling. It is a high heat supply experiment due to its heat resistance property. The test tube is burned in the burner by holding its neck with a clamp. Test tube is also used in bioscience for handling bacteria. Urine blood and IVF also takes place in test tubes.
There are some variants of test tube:
-Centrifuge tube: As per as the name suggests it is used in machines that can spin and separate solid from liquid chemical solutions. It is made up of plastic or glass and looks like a small test tube.
-Ignition tube: It is made up of soft glass and smaller as compared to a normal test tube. Like fusion tubes it is also used in sodium fusion. It is the tube which is disposable.

Note:
Fusion tube is used in the Lassaigne test which is used for determination of the presence of sulphur, halogen and nitrogen in organic compounds.
