The Mass Transfer And Diffusion Coefficients Unit allows to study the gaseous end liquid diffusion phenomena. It is very simple to use and requires very little maintenance besides it is composed of two distinct apparatuses which can be separately supplied:
The bath temperature is measured by a bulb thermometer and regulated by a thermostat; it is possible to measure with accuracy the liquid level in the capillary tube by means of an eyepiece and a Vernier scale. Apparatus for the study of the gaseous diffusion coefficient: It is composed of a thermostatic bath where a Tee shaped capillary tube is placed containing the liquid to be tested.
A magnetic stirrer constantly mixes the glass content, whose conductivity can be measured by means of portable conductivity meter and recorded by means of a proper software. Apparatus for the study of the liquid diffusion coefficient: It is composed of a glass vessel containing distilled water; a diffusion cell is placed in the vessel; the test liquid is passed through the cell.
Amplifier as matching element between signal voltage levels and standard voltages used in automatic control systems.

Materials Engineering Learning System uses industrial quality components to teach students how to evaluate and use different industry grade materials. The Materials Engineering Learning System allows students to conduct a wide array of tests including tensile testing on steel alloys.
Material strength properties affect the performance and safety of almost every product made. As technology has advanced, material choices have broadened and become more complex. Students learn industry-relevant skills in materials testing (tensile, compression, hardness, and shear), computerized data acquisition, chemistry of metals, interpretation of industry-standard numeric identification systems of various types of metals (steel, aluminum, brass, and copper), material strength analysis, and product design. Engineers and technicians alike must be able to select the proper material for an application and analyze material properties when a product fails.
Features:
Excellent preparation for study of engineering, manufacturing, industrial maintenance
Data analysis and problem solving
Understanding of realistic array of industrial materials such as steel, copper, aluminum, and brass
Visualization of material stress
Industrial quality components and relevant skills.
The machine tests any suitably shaped specimens of various materials. A hydraulic tensile and Brinell hardness testing machine. Thematerial must not exceed the maximum strength or hardness limits.
The load frame is mounted on adjustable legs. The display unitshows force and works as an interface to send data to a suitable computer. To applyloads, students pump a handle connected to a hydraulic pump. The extensometer has a digital display of extension and connects to the displayunit for data capture.
The main parts of the equipment are:
A ball indenter for Brinell hardness tests
An extensometer with a digital display for tensile tests
A load frame
A display unit with a digital display of force.
A solid understanding of the properties of materials is essential for technical and scientific professions. The materials test provides the necessary data in a reproducible and precisely quantified manner. This knowledge helps select the suitable material, monitor production and processing and ensure the requirements in terms of a component. The tensile test, bending test and hardness test are all part of classic destructive materials testing.
Features:
Compact, simple experimental unit for basic destructive tests
Tensile tests, Brinell hardness test
Learning Objectives And Experiments:
Tensile tests
Together with the accessories
Compression tests
Bending tests
Plot stress strain diagrams
Brinell hardness test
Testing of plate and coil springs
