One atomic beam, two spots: direct evidence of quantized angular momentum, on a benchtop.
The Stern-Gerlach experiment demonstrates that the spatial orientation of angular momentum is quantized. More than 100 years have passed since the experiment was first carried out by Stern and Gerlach. Today’s technical possibilities make it possible to perform this experiment using an apparatus that is both compact and easy to operate.

Turn up the inhomogeneous magnetic field and scan the detector. The single atomic beam splits cleanly into two.
Bring this to your lab →A beam of atoms travels through the apparatus toward the detector.
An inhomogeneous field deflects atoms according to the orientation of their magnetic moment.
Moving the detector across the beam shows one peak with the field off and two separate peaks with it on.
Typical result: a single beam profile splits into two peaks when the field is applied (illustrative).
Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.
Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.
Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
