Precise Determinations of Photoelectric Effect

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

High precision, quantitative atomic spectra experiment.

Design and create fantastic structures while learning about Newton's Laws.

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

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

Measuring apparatus for investigating the elastic deformation of rods of flat geometry and for determining the modulus of elasticity.

Measure the wavelength and threshold voltage of an LED and calculate Planck’s constant.

Basic apparatus for providing contact, power supply and support to a germanium crystal on a circuit board in experiments on the Hall effect or on conductivity. Includes an integrated, adjustable constant current source to provide the current through the sample, a measuring amplifier with offset compensation for Hall voltages and heating to raise the crystal to as high as 170 °C, also featuring temperature regulation and a switchable display showing Hall voltage, sample current, sample voltage or temperature.

Classic experiment that yields basic evidence for the existence of quantum states.

Updated, Compact Zeeman Effect Apparatus uses a high resolution Fabry-Perot interferometer and a USB video camera

Utilize the power of a spectrometer to investigate surface plasma resonance.

Precision apparatus uses sound waves to clearly illustrate the often poorly understood phase and group velocity concepts
