"micro tube racks"

Students measure pressure with a precision manometer.

Hertz electron tube for quantitative investigations of Inelastic collisions of electrons with inert gas atoms.

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

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.

Explore beautiful 3-D patterns created by a magnetic field mess free.

High quality and reliable.

Study Wavelengths and Energy All With One Device

Used to investigate wavelength in air.

Demonstrate the classic free fall experiment in a vacuum.

Demonstrates static electricity's attractive and repulsive forces using a pendulum electroscope.​

Demonstrate the Lorentz force and calculate the charge/mass ratio of an electron.

Bulk balsa, chipboard sheets, and dowels for blade making in the classroom.

Clear Measurements in Classic Study of Electrons

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.
