Choose your X-ray tube

Copper covers most experiments. Add any others you need, or none if your lab already has tubes.

3

Add extension sets

Each set adds the components and experiment guides for one field of X-ray science.

Try it yourself

Turn up the tube voltage

Raise the high voltage and watch the spectrum's maximum energy climb. The copper K lines only appear once the voltage passes about 9 kV.

What your students will do
1

Choose the experiment

Fit the goniometer, detector or sample stage your course calls for inside the spacious experiment chamber.

2

Set tube voltage and current

Dial in 5 to 35 kV and 0.01 to 1.0 mA precisely, in small steps, for clean, repeatable spectra.

3

Record and analyze

Capture X-ray spectra and diffraction patterns, then connect results to Bragg's law, Moseley's law and atomic structure.

Common questions
Does it work on U.S. power?

Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.

What else do I need to run the experiment?

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.

Can grant funding cover this?

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.
