Natural Sciences on the Board

The System The system „Complete Experiments: Chemistry“ allows you to set up glass apparatus in an easy

Complete Experiments Chemistry / Biotechnology

and clear way. The glass equipment can be clearly distinguished from the dark blue background of the large-format carrier panel.

Due to the sharp contrast between this background and the glass equipment, the students can clearly recognise and comprehend the experimental set-up. The fastening elements for the glass equipment are hardly visible. Thus only the experiment and no distracting support material catches the eye.

Rapid exchange of experimental set-ups:

Several holders are available for mounting the

out of the cabinet

various experimental set-ups. These can be fitted into the perforations of the matrix panel

onto the frame

wherever they are needed. Thus numerous ex-

that’s all

perimental arrangements are possible some of which are shown in this brochure.

The experimental set-ups can remain on the panel which can then be taken off the frame and stored in a special rack system. It is thus possible to prepare several complete experiments (as indicated by the name „Complete Experiments: Chemistry“) in advance and to store them for immediate use whenever they are needed. During class, the experiments which are no longer needed can be removed and replaced very quickly.

Mechanics

Resolution of forces on an inclined plane The angle of the inclined plane can be read off in a direct way using the magneto-adhesive optical (angular) disc. The marking arrows serve for showing the direction of the weight, of the down-slope driving force and of the normal force. It is also possible to draw force arrows of the correct length onto the board using water-soluble pens thus allowing to develop the parallelogram of forces.

Fixed pulley Has a fixed pulley by means of which a weight is to be lifted got any influence on the force needed for this purpose?

This question can be answered using a wide range of demonstrative material such as rulers, arrows and lettering on the board.

Restoring force on a displaced pendulum If a thread pendulum is displaced and released again, it tries to reach its resting position and starts to swing. In the experiment shown in the picture the pendulum is held at its maximum deflection by a torsion dynamometer. The force indicated by this dynamometer corresponds to the restoring force of the pendulum. Whether this force depends on the deflection of the pendulum or not can be tested in the course of the experiment.

Mechanics

Uniformly accelerated motion The track is fixed on the demonstration board with the aid of two magneto-adhesive holders. Light barriers serve for recording the motion of the model car.

The new universal timer 4-4 (13605.99) can be attached to the top of the board for demonstration purposes.

Horizontal and diagonal motion of projection There is no demonstrative method for showing the horizontal and diagonal motion of projection in a better way than by using a continuous water jet. The discharge vessel contains about 1 litre of water thus giving the experimenter enough time to explain all aspects of the motion of projection in the course of the experiment.

It is especially impressive to change the angle of projection while the water flows out.

Energy transformation during upward & downward runs A special feature of the PHYWE mechanics equipment for the magnetic board is the flexible track which allows you to set up completely unconventional track shapes for the experiments. The experiment here shows an upward and downward track (rollercoaster) which serves for demonstrating the transformation of potential energy into kinetic energy and vice versa. The flexible track can be bent in a wide range of different shapes.

The outer rim is fitted with a raised border to keep the model car or little balls, which can also be used for the experiments, on the track.

Thermodynamics

Absorption of thermal radiation

Utilisation of solar energy

Experiments using a solar collector The clamp on holder no. 02164.00 is attached to the aluminium frame of the demonstration board to hold a reflector lamp. The absorber plates of the solar collector no. 02165.00 allow you to study, for instance, the influence of the colour of the absorber. Large-format display units for indicating the temperature and time values can be attached to the board.

The solar collector can also be used to heat water flowing through the collector. The increase in temperature depends on the volumetric flow of the water.

Experiments on thermal expansion The measurement of the volumetric expansion of gases at constant pressure can be done using a U-tube manometer with mobile legs. The heated air volume expands thus displacing the right leg until the water

is on the same level in both legs again (p = constant). The volumetric expansion can be measured with the aid of the measuring scale and marked by means of coloured arrows.

The measurement concerning the linear expansion of solid bodies can be carried out using a metal tube which is tightly fixed at one end while the other end rests on an indicator. When hot steam passes through the tube, the tube expands. The deflection of the indicator can be marked with the aid of magneto-adhesive arrows.

Chemistry

Chemical fountains Some gases, such as hydrogen chloride, are extremely soluble in water. 1 liter of water solubilises approx. 443 liters of hydrogen chloride at 20°C. In a closed flask the gas gets in contact with water resulting in low pressure which draws more water into the flask. This is the basic principle of a chemical fountain, an exciting experiment for demonstrating the solubility of gases in water.

In the shown version, the production of the hydrogen chloride, the filling and the sputtering of the fountain flask occur in one and the same apparatus.

Easy to set-up: in the manual a drawing shows the positioning of the holders and the picture shows the assembly of the items.

Faraday's law An electrical current through a solution may result in conversion of substances. The current is the driving force of the concurrent redox reactions.

During electrolysis of water which is made conductive by the addition of ions, hydrogen is formed at the cathode and oxygen at the anode. By separate collection of the gases (e.g. using the electrolysis apparatus – Hofmann type) the reaction can be observed in a quantitative way and both the Faraday’s laws can be derived.

The first law proves that the amount of substance produced during electrolysis is proportional to the amount of charge which flowed through the solution.

The second law proves that the electrochemical equivalents of elements behave to each other in the same way as their equivalent masses (molecular mass divided by the valency).

Both laws can be derived in demonstrative experiments using the shown set up.

Chemistry

PEM fuel cell The PEM (proton exchange membrane) technology is the fuel cell type favoured by automobile manufacturers and the manufacturers of combined heat and power stations.

In the demonstration set-up shown in the picture, hydrogen is produced the classic way in a gas generator by the reaction of hydrochloric acid on zinc. It is then passed through distilled water for cleaning. Inside the PEM fuel cell, the hydrogen is converted into water and electrical energy using oxygen (taken from the air). The electrical energy thus produced by the fuel cell is used to drive a small motor.

The advantage of the experimental set-up shown here is that this way to generate hydrogen does not require an external power supply (electrolysis) or a pressure gas container. One can generate as much hydrogen as one needs and whenever one needs it in a particularly simple way.

Fused-salt electrolysis The fused-salt electrolysis of sodium chloride to produce chlorine and sodium which can be further processed and turned into caustic soda solution is an important commercial-scale process. The experiment shown in the picture allows demonstration of the important steps of this process in a simple way. However, as the melting point of sodium chloride is extremely high, lead chloride with a significantly lower melting point is used as the model substance.

Chemistry

Model experiment on the desulphurisation of flue gas At an average, German black coal contains 1 ton of sulphur in 100 tons of coal. During combustion thereof, 2 tons of sulphur dioxide are formed. Therefore a large power plant with a power of 700 MW which burns approx. 200 tons of black coal per hour produces approx.

100 tons of sulphur dioxide each day. Such large amounts of pollutant cannot be blown into the air, the flue gas must be desulphurised.

The model experiment shows the chemical processes of desulphurisation of flue gas in a simplified manner such as take place in power plants today. The clear and compact set-up and simplification compared to an industrial process makes it easy to understand this procedure.

Gas chromatography The shown didactical set-up for demon-stration of gas chromatography in a tempera-ture range up to 100°C suits well for an introduction to the principles of the gas chromatographic separation of mixtures of substances.

The stationary phase of the gas separating column can be easily be self-filled at low costs, e.g. using dinonylphthalate adhered to diatomaceous earth. Helium gas is used as a carrier. A NTC temperature probe shows the thermal conductivity of the separated components of a mixture as a signal which can be recorded via the control unit of a plotter or on a PC interface.

The modular set-up allows the identification of every component which is used in the process in a simple way.

These components are not observable in the commercially used chromatographs due to their compact design.

The separating column and its heating mantel are manufactured out of glass. So, exactly where the separation of the mixture happens is completely transparent.

The amplified signal of the heat conductivity sensor can be comfortably recorded using an interface like the shown Cobra3 CHEM-UNIT.

Microbial synthesis of ethanol by means of Zymomonas mobilis Zymomonas mobilis proved to be much more efficient than yeast in the synthesis of ethanol.

In this experiment, Zymomonas mobilis is fermented in a bioreactor. The experimental set-up is quite simple. The inoculated reactor pot is placed in a hotwater bath on a magnetic stirrer and a hotplate assuring temperature control and thorough mixing. It is not necessary to withdraw consumed medium or to add fresh medium as this is a static culture also known as a batch culture.

The samples taken can be submitted to a photometric determination of the cell density. Apart from that it is also possible to determine the number of cells in a counting chamber in order to set up a growth curve.

Chemical or enzymatic tests show the consumption of glucose and the production of ethanol.

Biotechnology

Biotechnological production of ethanol Biotechnological production methods are becoming increasingly important. Every day, the list of products produced with the aid of bacteria, yeast or certain cell cultures gets longer and longer. Production takes place in so-called bioreactors (fermenters) allowing control of the mixing, the aeration, the pH-value, the temperature etc. in a very precise way. However, these fermenters are too complicated for being used in class. The bubble bioreactor shown in the picture is not only very simple but also an optimum, low-cost solution for experiments in the field of education. To demonstrate the function of such a reactor, molasses (sugar production waste product) can be fermented to ethanol in a so-called batch process.

Bacteria in the service of mining In the 1950’s, the importance of certain bacteria for the extraction of metals out of ores was discovered.

Nowadays, microbial ore leaching of so-called lowgrade ores constitutes more than 10 % of the total production of copper in the USA alone.

The bioreactor shown in the picture serves to demonstrate this method of ore leaching (e.g. copper out of copper ores) with the aid of these bacteria (Thiobacillus ferrooxidans) in a very simple and comprehensive way.
