Van De Graaff Generator, Hand Driven
Catalogue No: 1080640
Hand operated, mounted on base. For the generation of electric charge, useful in electrostatics. Comprises a near spherical dome supported on top of an insulated, pillar on the base. A removable flat rubber belt rotates through rollers and results in the accumulation of charge on the dome, until electrical breakdown of air surrounding the sphere occurs. With sufficient charge build up on the dome, bringing the earthed discharge sphere sufficiently close to it results in the transfer of charge from dome to ground in the form of electric spark. Earthing terminal provided on the base. Supplied with discharge sphere with 4mm earthing socket, mounted on a long insulated handle.

Van De Graaff Generator, Motor Driven, Large
Catalogue No: 1080680
Bigger in size. Comprises a two piece (near spherical) dome of diameter 275mm approx., fixed on top of an acrylic pipe, with complete assembly mounted on a sturdy sheet metal casing. Additionally, the base also incorporates an electronic variable speed control for driving its heavy duty motor. The bigger size dome increases the charge capacity of the apparatus resulting in higher build up of electric potential. The charge buildup on dome is accelerated by heavy duty motor and other design changes incorporated in the device. Comes with a discharger mounted on a long insulated handle, one side of the discharger being hemispherical, while other pointed to allow an effective demonstration of lighting conductor.

Ventilation Apparatus
Catalogue No: 1061060
Demonstrates the principle of ventitation convection currents in air. Comprises a sheet metal enclosure with open sliding glass front and two circular openings at the top for mounting glass chimneys. Air heated by a candle placed beneath one of the chimneys with glass door closed, causes the flow of convection currents, which can be observed by bringing a smoldering string near the top of other unheated chimney. Supplied without candles.

Venturi Tube Demonstrator
Catalogue No: 1020420
A simple device for the demonstration of Bernoulli’s Law. Similar devices fine extensive application in everything from carburetors of IC engines to aircraft airspeed indicators. Comprising of a horizontal glass tube having three cross sections along its length x wide, narrow and wide respectively, with wide cross-sections having same size.
One short, side tube projects from each of the three cross-sections for connecting to the manometric tubes. Also included is a three legged manometric tube joined to a common horizontal tube. When gas is flowing through the venturi tube with manometer filled with colored water, the relative pressure at the three points of the tube is evident from the water level in manometers.
