What Is The Thiele Tube?

The thiele tube is part of the glass instruments inside the chemistry laboratory. That its function is essential in the study of samples or substances, used to determine the purity and characteristic properties.

Definition of Thiele Tube

The Thiele tube is a type of laboratory apparatus used for measuring the mechanical properties of materials. It is named after the German physicist Ernst Thiele, who developed the concept in the early 20th century.

A Thiele tube consists of a cylindrical tube that is closed at one end and has a small hole or aperture at the other end. A sample of the material being tested is placed inside the tube, and the tube is then subjected to an axial compression or tension force. The deformation of the material inside the tube can then be measured and analyzed to determine its mechanical properties, such as its modulus of elasticity or strength.

Thiele tubes are commonly used in the field of materials science and engineering to study the mechanical properties of materials such as metals, polymers, composites, and ceramics. They are also used in research on the mechanical behavior of cells, tissues, and other biological materials.

The use of Thiele tubes allows researchers to study the mechanical properties of materials in a controlled and repeatable manner, without the need for complex and expensive testing equipment. This makes Thiele tubes a valuable tool for a wide range of research and development activities.

Thiele Tube types

There are several types of Thiele tubes, each designed for specific testing purposes and applications:

1. Compression Thiele tubes: These tubes are used to measure the mechanical properties of materials under compression. They typically have a closed end and an open end with a small aperture, through which the material is compressed.
2. Tension Thiele tubes: These tubes are used to measure the mechanical properties of materials under tension. They typically have an open end and a closed end with a small aperture, through which the material is pulled in tension.
3. Bending Thiele tubes: These tubes are used to measure the mechanical properties of materials under bending. They typically have a curved shape and are subjected to a bending moment, allowing the researcher to study the material's resistance to bending and its flexibility.
4. Torsion Thiele tubes: These tubes are used to measure the mechanical properties of materials under torsion, or twisting. They typically have a cylindrical shape and are subjected to a twisting moment, allowing the researcher to study the material's resistance to twisting and its torsional stiffness.
5. Fatigue Thiele tubes: These tubes are used to study the fatigue behavior of materials, which is their ability to withstand repeated loading and unloading cycles without failing. Fatigue Thiele tubes are subjected to repeated loading and unloading cycles, and the number of cycles required to cause failure is used to determine the material's fatigue behavior.

These are some of the most common types of Thiele tubes used in materials science and engineering research. Each type of Thiele tube has its own unique design features and capabilities, and the choice of which type to use will depend on the specific testing requirements and the mechanical properties being studied.

How do you use a Thiele tube?

Should have access to the instruments and materials as a tube with side arm, a thermometer, a single-threaded plug.  One or two capillary tubes, a thin garter or adjustment rubber. A universal bracket, a metal clamp, a grid of asbestos. A metal ring, a bunsen lighter, mineral oil or glycerin. Then proceed to, first introduce the solid or liquid sample in the capillary tube and to attach it with the garter or rubber band to the thermometer. Second, add the mineral oil to the container, up to a little above the arm side.

Mount the metal ring on the bracket with the asbestos grate above the burner flame. It is immediately locate the tube with the handle held by the metal clamp. Incorporate the thermometer attached to the capillary tube already prepared, without touching the walls, nor the bottom of the container. Light the bunsen lighter on the side arm with a proper call.

Thiele tube function

Due to its resemblance to a test tube there is no be confused with its usefulness. It is manipulated to look for the chemical property melting or boiling point. His arm side or handle, it is not to grab it over there but to supply heat. This heat moves in a circular fashion throughout the instrument with uniformity. Determine the concentration of the sample under study and its purity. Getting the melting or boiling temperature of the unknown sample.

Thiele Tube features

It was created by a German chemist, in 1917 named Johannes Thiele, as for its shape is a test tube with a handle. Manufactured in borosilicate glass, pyrex or, therefore, heat-resistant. Have measures 150 mm long x 40 mm wide.

• There is a variety in the sizes according to the precision at which the sample was subject.
• It is unique in its design and has no classes.
• The side arm serves to supply the heat not to grab it.
• The glycerin inside the container makes let the heat circulate evenly.
• The convection current causes the the temperature remains constant.
• The temperature is gradually increasing.
