"micro tube racks"

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

Investigate the deflection of electrons.

Investigate the wavelength of sound on an open end tube.

This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

Compares thermal expansion of various liquids.

Generate a uniform magnetic field perpendicular to the axis of the Teltron D series tubes.

Check valves allow one way passage of water or air through tubing.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

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.

The Solar Thermal Exploration Kit is modeled after a domestic solar water-heating system. Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat the water. Learn about what makes a solar water heating system more or less efficient.

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.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.
