Neon lamps
Supplier: PHYWE
Tubular glow lamp of glass. With conical contact hats at the ends. Used, inter alia, to determine the polarity of charge, because light only occurs around the negative electrode. Ignition voltage approximately 80 V, switching voltage approximately 65 V. For example, connects with crocodile clips.

Ballistic pendulum and throwing device
Supplier: PHYWE
With a few simple steps, the ballistic pendulum is quickly rebuilt into a throwing device with a variable/variable firing angle. The ballistic pendulum, a common method for determining the speed of a pistol bullet, is to push them into a sandbag. With the ballistic pendulum, a harmless variant of this experiment can be performed in the classroom.

Roller coaster
Supplier: PHYWE
The profile of the runway has been designed so that the experiments can be performed easily, quickly and safely. The length of the track (1,5 m) is more than sufficient for all conceivable physical experiments to be performed. The trolleys are equipped with overload protection in the form of a recessed, resilient wheel suspension. Characteristics.

Centrifugal power device with experimental trolley
Supplier: PHYWE
With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.

Millikanapparat
Supplier: PHYWE
Equipment for demonstration of the quantum properties of the electric charge, as well as to determine the elementary charge. The experiment is easy to perform and suitable for both laboratory and demonstration using the Videoflex camera (765-1000). With the equipment, the elemental charge can be determined in 3 ways: change of charge by means of an alpha radiator, falling and rising speed with constant capacitor voltage and free voltage and falling speed without electric field.

Diver, Cartesian
Supplier: PHYWE
Divers of glass, placed in a bottle filled with water. If the liquid pressure increases, water flows into the diver, whose average density increases. This results in the diver sinking to rise again towards the surface when the pressure is reduced.

Rocket
Supplier: PHYWE
For demonstration of the rocket principle. The model is half filled with water and placed on a launch pad. An internal overpressure is inflated with an air pump. The rocket is released manually and then flies freely longer than 40 m. Can also be propelled with a carbon dioxide cartridge along a tensioned line. The rocket's traction force, with carbon dioxide cartridge as the driving source, can be measured with a dynamometer and amounts to about 0.3 N.

Voltmeter, electrostatic
Supplier: PHYWE
Demonstration instrument for lossless measurement of DC and AC voltages. Due to the high insulation resistance (approx. 1014 ©), the instrument loads the voltage source insignificantly. At the same time, the voltage drop becomes negligible. The measuring systems are protected against disturbing fields and placed in plastic apparatus housings. The measurement can be studied from the back through a window. The large and clear scale and the design of the pointer make the instrument very easy to read even at longer distances. The scaling of the scale enables precision reading. Scale is also available on the back. The pointer is visible through a slit in the scale. Mechanical zero adjustment with thumbwheel. Protected against overload by flashing over spark gap. Connection with banana connectors to high voltage insulator and two sockets for ground connection on the top of the instrument. Used in electrostatic tests, often together with power supplies 765-1325 or eg for examination of the charge density on Faraday cages, conductors etc.

X-ray equipment
Supplier: PHYWE
Phywe's new X-ray equipment is specially developed for teaching purposes. Used in laboratory work and demonstrations from the simplest transilluminations to Bragg diffraction and Compton scattering. Tungsten is normally used as a cathode in X-ray tubes. This means that the voltage must be up to about 65 kV before X-rays are formed. Phywe's X-ray tubes only need 10 to 12 kV for the process to start. For the X-ray equipment, there are 3 different X-ray tubes with the anodes made of Cu, Mo and Fe. These are built as plug-in modules and are replaced in a few seconds. Most laboratories can be connected to Phywe's data measurement system COBRA. The X-ray cabinet is equipped with a large space for experimental setups, clearly visible through a sliding door of acrylic plastic containing lead particles. Two safety switches are connected to the door. The equipment meets the EU requirements for X-ray equipment and is CE Approved.
