Device for experiment-based determinations of the dependence between the volume and pressure of a gas at constant temperature (Boyle's law).
Consists of a plexiglass cylinder with graduations for volume measurement, piston, manometer and air inlet / outlet valves.
Turning the handle moves the piston via a thread in the plexiglass cylinder. This allows a generation of overpressures and underpressures. For safety reasons, the power cylinder is enclosed in another plexiglass cylinder.
