Periodic System poster 120×85 cm
Periodic System poster 120×85 cmDouble-sided periodic table with pictures of the individual elements printed on durable plasticized cardboard.
The poster shows on one side the classic information for each element, including atomic number, atomic mass, and other standard data. On the other side, each element is illustrated with a picture showing what it looks like in its purest form, or where it is typically found in combination with other substances.

Photocell unit for mounting on stand
Photocell unit for mounting on standFor pendulum period measurements, air track timing, measuring period of rotation etc. It connects to electronic counters of type 200250 or 200260 using the supplied cable with DIN plug. Made from impact-resistant plastic with threads for vertical and horizontal mounting using the supplied Ø 10 mm support post.
Photodetector
PhotodetectorThe photodetector can be used to demonstrate communication by laser light, fibre optic communication, plotting of interference patterns etc.
Physical pendulum/Bessel pendulum
Physical pendulum/Bessel pendulumThe physical pendulum is used to study moments of inertia and the motion of rigid bodies. The centre of gravity, pivot point and moment of inertia can be varied in innumerable ways. For calculation, Steiner’s theorem is useful, as well as a number of formulae for moments of inertia of the pendulum’s different components.
Pipette filler Peleus bulb

The ball is equipped with three valves for controlling suction and discharge from the pipettes.
Planetarium, Helios
Planetarium, HeliosHelios is a mechanical planetarium that models the Solar System with Mercury, Venus, Earth (with moon), Mars, Jupiter and Saturn in correct relative orbital speeds. The speed can be adjusted continuously – forwards and backwards – so that phenomena such as the retrograde motion of Mars can be clearly demonstrated. The removable dome shows the northern starry sky, and a separate 100 mm globe of the Earth is included for seasons, day and moon phases.
Planetarium, mini model
Planetarium, mini modelThe Planetarium mini model is an educational and fascinating representation of the solar system, where students can observe the movements of the planets and the Moon around the Sun.
