Brownian Motion Demonstrator
|
|
|
This apparatus consists of a glass smoke cell, a cylindrical Whitley Bay pattern condensing lens, and a laser source. Students can observe Brownian motion of smoke particles in the smoke cell on the work stage of a microscope.

Magnetic Ringbom Stirling Engine
|
|
|
The Ringbom Stirling Engine operates on low heat and uses a magnet instead of a piston to drive the piston!

Thermoacoutsitc Stirling Engine
|
|
|
Thermoacoustic devices are very different from Stirling devices, although the individual path traveled by each working gas molecule does follow a real Stirling cycle. These devices include the thermoacoustic engine and thermoacoustic refrigerator(cold side).

Small Brass Steam Engine
|
|
|
This impressive little single-piston steam engine works as good as it looks! It stands just under 5" tall with a 1-1/4" diameter wheel. Water is heated in the chamber (note: flame is used in operating this product). The steam pushes the piston and makes the wheel spin.

Thermoelectric Effects Apparatus
|
|
|
PLEASE NOTE: Advanced Physics Equipment is built-upon-order. We do not stock these items in house, but order them built when an order is placed. Build orders take approximately 90 days.
• Investigate the thermal characteristics of three electrical thermometry devices
• Explore the features and behavior of a closed loop digital temperature control system
The Thermoelectric Effects Apparatus consists of an oven containing a cooling fan, a massive metal block and electric heater supported on two thin struts, the three samples, and the control system sensor. A control unit provides the heating current and houses the digital temperature controller. The oven and the control unit are connected by three multi-pole cables.
The sample devices are a thermocouple, a three-pole metal resistor, and a thermistor. An insulated flask is provided to hold ice water for the cold junction of the thermocouple. The signals from the three sample devices can be read by any suitable measuring device provided by the user connected to the outputs of the control unit (for example, digital multimeters.)
The digital control system can be operated in P, PI, PD, or PID mode to show their characteristics when controlling the oven temperature with or without fan cooling. A wide range of parameters and alarms can be set to explore their effects.
