Supplier: PHYWE

Glass tube used to demonstrate standing waves and acoustical forces. When used in conjunction with a sound source (single frequency), plunger to alter the effective length of the tube and cork dust or talcum powder, the tube can be made to resonate and the powder will aggregate at nodes in the tube. Calculation of the wavelength and speed of sound can be calculated from the measurement of these nodes.

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.

Very stable and versatile A-foot with 6 mounting holes for various accessories. 2 of the 3 rubber feet have individual level adjustment. Made of cast, lacquered zinc alloy. Intended for cylindrical stand rods 6 to 14 mm and/or square stand rods with a cross section of 6×6 to 12×12 mm.

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.

Apparatus for detecting that the pressure at the bottom of a container does not depend on its design, but only on the liquid level. For quantitative determination of the hydrostatic pressure and examination of the linear relationship between pressure and liquid level. The liquid pressure at the bottom of the various vessels deforms a highly elastic rubber membrane whose movement is transmitted to a centimeter-graded needle. The deviation can be compensated with weights. The mass and distance of the weight from the pivot point make it possible to quantitatively determine the pressure change. A second pointer can be mounted vertically to visualize fluid level.

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.
