Pool chemicals can normally be measured by using test strips or a test kit that can be obtained at most stores.
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass

The function of a hard glass test tube is heating a substance. The glass is resistant to chemicals and it can withstand pressure and heat.
Heating should be slow.The test tube should not be full.Work in a laboratory hood.
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.
