Ideal Gas Law Apparatus - TD-8596A


Shown in use with an Absolute Pressure/Temperature Sensor


Investigating the Ideal Gas Law is simple using our Ideal Gas Law Apparatus. By connecting a Pressure Sensor and a Temperature Sensor to this syringe, students can quantitatively look at the relationships between pressure, temperature and volume.

The large syringe ensures accurate volume measurements and the stable design (updated for 2010) means consistently repeatable results as well as long term reliability.

Typical Applications

  • Discover or verify the Ideal Gas Law
  • Investigate relationships such as pressure vs. temperature (Gay-Lussac's Law), pressure vs. volume (Boyle's Law) and temperature vs. volume (Charles' Law)
  • Calculate the number of moles of air in the syringe based on pressure, temperature and volume measurements


  • Ideal Gas Law Syringe
  • Built-in Fast Response Thermistor Probe
  • Quick Connect Pressure Port
  • How It Works

    A low thermal mass thermistor is mounted within the syringe for real-time measurement of temperature changes inside the syringe. Tubing and a quick connect port allows a Pressure Sensor to be directly connected to the syringe. As the plunger of the syringe is depressed, the volume decreases while pressure and temperature increase. The data will help students better understand the Ideal Gas Law.

    PV = nRT

    A mechanical stop is included on the syringe plunger to prevent damage of the thermistor within the syringe and to allow quick (adiabatic) volume changes.
