Completely re-engineered, the Critical Point Apparatusis a precision device for investigating compressibility and liquefaction of a gas. Measurements allow the critical point for the gas to be determined as well as the recording of isotherms for an adiabatic p-V diagram(Clapeyron diagram). This unique equipment set is made in Germany and needs no mercury!

The Deluxe Stirling Engine can be operated in three modes: as a heat engine, heat pump and refrigerating machine. The sleek, modern design permits clear observation of individual sequences of motion at all times.

The Apparatus for Demonstrating the Greenhouse Effect allows you to conduct simple, lucid, quick demonstrations of the effect of greenhouse gases on the absorption of infrared radiation. «««
