Specification for Test Tubes and Boiling Tubes:

Test tubes and boiling tubes are essential laboratory glassware used for holding, mixing, and heating chemical substances.

Test Tubes:

  • Smaller in size compared to boiling tubes.
  • Used for handling small quantities of liquids and conducting experiments at moderate temperatures.
  • Often have a rounded bottom and an open top.

Boiling Tubes:

  • Made of heat-resistant glass such as borosilicate.
  • Larger and thicker than test tubes to withstand high temperatures.
  • Designed for heating substances directly over a flame or in boiling water.
  • Feature a uniform diameter and open top with a rounded bottom.

Specifies length, external diameter and two alternative wall thicknesses, with tolerances on each, for eight sizes of test tubes and boiling tubes made of soda glass or borosilicate glass and suitable for general laboratory use.

Also specifies the finish of the top of the tubes and the type of borosilicate glass.
