The Crystallization Vessel study unit allows to acquire a basic knowledge of the crystallization process and the principles underlying it. It allows to carry out experiments concerning the separation of a solidifying solute from a liquid solvent in which it is dissolved, either by evaporating the solvent or by cooling down the solution. The study unit is supplied with manuals which describe all parts of the trainer, the installation and utilisation procedures, as well as many exercises with the relative results. That allows to perform crystallization tests on salts with a positive or negative solubility course according to the temperature.
Experiments:
Evaluation of the crystallization efficiency.
Plotting of the solution solubility curve according to the temperature.
Crystallization by evaporating the solvent.
Crystallization by cooling the solution.

It is microprocessor-controlled and contains a calibrated pressure transducer. The unit has an integral liquid crystal display that allows the user to read pressure directly. The signals ofthe pressure sensors may be output to optional Versatile Data Acquisition System. The Differential Pressure Transducer and readout is an optionalancillary to Subsonic Wind Tunnel. The control and instrumentation panel of the wind tunnel includes a location for mounting up totwo Differential Pressure Transducer modules. Using enables accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer. It measures and displays pressures in Pitot-static tubes and other pressure-sensing devices fitted to a wind tunnel, with respect to the atmosphere or differential pressures. Many readings can be taken and the user may usea suitable spreadsheet software package to obtain a more accurate overview ofpressure distributions. When the Differential Pressure Transducer is used with the automatic dataacquisition unit it provides a significant advantage over conventional instruments such as manometers.

Free Vibrations Of A Mass Spring System fits to the sturdy Test Frame for study or demonstration. A back panel fixes to the Test Frame. The panel holds two vertical guide rods and a non-contacting displacement sensor. A test spring suspends a balanced mass platform which vibrates vertically in the guide rods. Therefore, students can easily make the link to simple harmonic motion - defined as the oscillatory motion where the restoring force is proportional to the displacement. The mass-spring system is one of the most easily explainable oscillatory systems. This is because students may already be familiar with Hookes Law, showing the force exerted by a spring is proportional to the extension.
Free Vibrations Of A Mass Spring System is part of a range that explores free vibrations in simple one degree of freedom systems.
It introduces students to key scientific terms such as:
Spring constant and Hookes Law
Oscillation damping

Ultrasonic fetal heart detectors are low-cost devices used in a variety of healthcare settings to provide audible and visual information about the fetus. The primary purpose of the fetal heart detector is to provide quick reassurance of fetal well-being to both the mother and the healthcare worker. Certain conditions, such as vaginal bleeding or lack of fetal movement, can cause anxiety in the mother, making her question the health of her unborn baby. Ultrasonic fetal heart detectors can easily detect fetal heart motion throughout the pregnancy, starting as early as 8 weeks. The fetal heartbeat cannot be heard with an obstetric stethoscope until 24 weeks after conception.

The equipment consists ofa vertical panel that holds a clear plastic quadrant, to which students addwater. The quadrant has engraved lines to help students keep the plane in avertical or angled position. The cylindrical sides of the quadrant have theircentral axis coincidental with the moment measurement axis. This product allows students to measure the moment due tothe fluid (hydrostatic) thrust on a fully or partially submerged plane. The plane works in either a vertical or inclined (angled) position. Students thencompare their measurements with theoretical analysis. The total fluid pressures on these curved surfaces therefore exert no moment about this pivot.Therefore, the moment is only due to the fluid pressure on the plane testsurface. Students measure this moment using weights suspended from a level arm. A scale on the panel of the apparatus shows the head of water. They then initially balance the quadrant tank using one of the weighthangers and the smaller trimming tank. They take results by balancingincremental weights on the hanger with known quantities of water. To performexperiments, students level the apparatus using its levelling feet and spirit(bubble) level. They decide whether to test either a vertical or inclinedplane. Students note the relationship between the moment and the water height(h). They then usethe results to calculate the equivalent moment of force (M) or hydrostaticthrust.
