Gas Laws Demonstration Unit
Product Code : JA-HTLE-9205
The Gas Laws Demonstration Unit (SKU JA-HTLE-9205), supplied by JaincoLab, is a small bench-top unit for investigating the first law of thermodynamics with the perfect gas law and the expansion of air. Two vessels are joined by a large-bore pipe and valve, and an integral pump can pressurise one vessel and evacuate the other. This gas laws demonstration unit records the air temperature in each vessel with low-inertia thermocouples and the pressures with transducers.
Specifications
The gas laws unit is specified by two impact-resistant plastic vessels, a large-bore interconnecting pipe and valve, an integral air pump, extra valves for isolation and venting, pressure switches that limit the working pressure, thermocouples and pressure transducers. Vessel volumes are confirmed on the quotation.

Experiments with the gas laws demonstration unit
The unit is used to study how the pressure and temperature of air change when it is compressed, expanded or allowed to flow from a pressurised vessel into an evacuated one.
- Perfect gas law and the relation between pressure, volume and temperature
- First law of thermodynamics applied to the expansion of air
- Expansion from a pressurised vessel into an evacuated vessel
- Venting to and from the atmosphere

Frequently asked questions
What does the pump do?
It can pressurise one vessel and evacuate the other, so that expansion between them can be studied.
How are readings taken?
Thermocouples measure the air temperature in each vessel and transducers measure each chamber pressure.
How is overpressure prevented?
Pressure switches limit the operating pressures.
What should a quotation request include?
Send the SKU JA-HTLE-9205, whether a display unit is needed, the quantity and the delivery destination.
