Quantify real-gas behavior with CO₂ and N₂ in a single lab session.


A stream of gas is fed to a throttling point, where the gas ( CO 2 or N 2 ) undergoes adiabatic expansion. The differences in temperature established between the two sides of the throttle point are measured at various pressures and the Joule-Thomson coefficients of the gases in question are calculated.
All units adapted for 110V/60Hz. Contact us for volume pricing and grant assistance.
Set the pressure drop and choose the gas. CO₂ cools far more than N₂ for the same expansion.
Bring this to your lab →A steady stream of CO₂ or N₂ flows to the throttling point, where it expands adiabatically.
Sensors on both sides of the throttle record the temperature change at several pressures.
Students plot temperature drop against pressure difference and determine each gas's Joule-Thomson coefficient.
Typical student results: CO₂ cools much more than N₂ for the same pressure drop (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.
