Electron Deflection Tube Demonstration Series
Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

High Voltage Power Supply 5000 V
Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Vibration Generator
Vibration generator for exciting oscillating and waves mechanically, such as in coil springs, a rubber cord, a wire ring or a Chladni plate. In robust plastic housing including mounting pin with 4mm socket for attaching accessories (Chladni plates, resonance wire, rubber band, etc.). Including holder for stand rod (up to 8mm dia.) on the rear side of the apparatus for the demonstration of standing waves in a coil spring. The generator is equipped with overload protection and is driven by a loudspeaker for smooth oscillations and fine travel stepping.

Whiteboard Mechanics Kit
The mechanics kit for whiteboard demonstrations includes more than 25 large, colored, and easily distinguished components stored in a case with foam inlay. More than 30 experiments can be set up in rapid time. Large components ensure that experiments can be viewed from a distance. Secure attachment is guaranteed by high-grade AlNiCo magnets, allowing quick and easy configuration of experiments. Measuring units, vector diagrams, and explanations can be provided right next to the experimental configuration on the blackboard.

Free Fall Apparatus
Apparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate. Includes 3 steel balls. A micro-magnet holds the ball in its start position. Three contact pins under the release mechanism ensure that the start position of the ball can be reproduced and act as the contacts of a switch that opens when the ball is released, thus triggering the beginning of the timing measurement. When the ball strikes the contact plate at the bottom, the timer is stopped. The ball is also held firmly on the plate so that it does not bounce. The height through which the ball drops can be adjusted to a fraction of a millimeter and read off a scale on the column.

Advanced Radioactivity Kit
Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).
