Shows that the bottom pressure in a liquid depends only on the height and not the shape of the container. The fluid pressure is transferred via a rubber diaphragm to an adjustable hand. Comes with four containers of different shapes. Dimensions.

Supplier: GR NNA PLASTEMBALLAGE AB

Trolley, 100 g, of lacquered sheet metal with nylon wheels. Equipped with hook and hole for mounting weights.

Supplier: CORNELSEN EXPERIMENTA

Intended for use on overhead projectors for demonstration of function and principle for different types of motors. Made of strong, transparent plastic. Equipped with suction feet.

Supplier: CORNELSEN EXPERIMENTA

Bicycle dynamo with transparent housing. Consists of magnetic anchor and coil mounted on base with belt drive. Equipped with connections for 4 mm banana plug and light bulb 3.5 V/0.2 A.

Supplier: GR NNA PLASTEMBALLAGE AB

Ribbons with elderflower balls suspended in thin threads. Placed around the head of a person who stands on an insulating surface and can be charged with the help of a belt generator. The balls stand out correctly. The belt can also be placed directly on the belt of the belt generator.

Supplier: PHYWE

Ice cream sphere filled with noble gas of low pressure. The tube's two cylindrical necks are protected by plastic sleeves and are designed to fit in Helmholtz coils 765-1207. The tube is used to show how an electron beam is deflected in a magnetic field. If the tube is in a homogeneous magnetic field with sufficient strength, the electron beam becomes circular. The tube is equipped with an internal measuring scale with fluorescent markings at distances of 4, 6, 8 and 10 cm (2r) from the cathode. The tube is well suited for determining the charge-mass ratio of the electron with great accuracy.

Supplier: GR NNA PLASTEMBALLAGE AB

Used to show the effect of air resistance in free fall. An air pump or water suction is used to evacuate the air in the pipe. Supplied with: 1 glass tube, 2 rubber plugs, one of which with a crane tube. 3 test specimens of resp. down, plastic and lead.

Supplier: PHYWE

Same as 765-1149 but without painting. 50 components incl. Manual.

Supplier: CORNELSEN EXPERIMENTA

For experiments with absorption of heat radiation. Consists of a black and a white E-flask and two thermometers (0 to 50 °C).

Supplier: CORNELSEN EXPERIMENTA

72 series-connected semiconductor elements, mounted between two ceramic plates which in turn are attached to heat-conducting metal. If the metals are exposed to different temperatures, a voltage arises, sufficient to drive, for example, a slightly rotating motor. The thermogenerator can also be run in the other direction, ie. a voltage is connected and a temperature difference is obtained across the metal legs.

Supplier: PHYWE

Precision capacitor for electrostatic tests e.g. examination of the relationship between charge, voltage and capacitance. Measurement of the dielectric constant and the electrostatic induction constant. The permanently mounted plate is well insulated while the movable plate is mounted directly in the stand. The distance between the capacitor plates can be adjusted with an accuracy of 0.1 mm. Distance between plates 0 to 70 mm.

Supplier: PHYWE

TESS OE3 contains 19 components. With TESS OE3 as a complement to TESS OE1 and OE2, another 30 experiments can be performed in the field of wave optics. Delivered in a plywood box.

Supplier: PHYWE

Two identical coils with a diameter of 400 mm (2R), 154 turns of winding each and mounted on separate sockets with connection contacts. Distance between coils 200 mm (R). The coils are held together by three detachable rails. Two of these have brackets for wire beam tubes 765-1206. The coils are used, for example, to provide a homogeneous magnetic field in the wire beam tube. Suitable voltage: 7 V DC (well smoothed) if the coils are connected in parallel and 14 V DC for series connection.

Supplier: 3B Scientific

Function generator with external sweep function and power amplifier for use in versatile student and practical experiments covering simple harmonic oscillation, AC electricity and induction. Featuring illuminated, digital display for frequency, signal form, offset and other parameters.
