Description:   Easy and safe way to hold and power your tubes.

Description:   Gamma Spectroscopy detector.

Description:   This low-cost, portable unit instantly measures levels of harmful beta, gamma, and X radiations on its compressed scale meter.

Description:   This box shows Planck's Constant in action.

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

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

Description:   With this meter, you can survey for alpha, beta, and gamma radioactivity or monitor a work area.

Description:   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.

Description:   Robotics for grades 3 to 5.

Description:   Unique demonstration of the interaction of longitudinal sound waves and transverse light waves.

Description:   High quality and reliable.

Description:   The properties of radioactivity and the concept of half-life determination can be difficult subjects for students to fully understand.
