Neodymium magnets, Ø 6 x 8 mm
Neodymium magnets, Ø 6 x 8 mmThese magnets are so powerful that they can even demonstrate the properties of extremely weakly magnetic materials.
Neodymium ring magnets
Neodymium ring magnetsSet of 25 ring-shaped neodymium magnets. Put them on a pencil and make them hover.
NeoZoom, binocular
NeoZoom, binocularBinocular zoom stereo magnifier with stepless magnification between 7x and 45x. The stereo magnifier has good, sharp optics and powerful mechanics. The eyepieces have a large light opening (glasses-friendly), and thus you get the greatest possible pleasure from the beautiful and high-contrast image. Optical head with 45° oblique view, adjustable eyepiece distance and separate dioptre compensation.
Nervous System, Relief Model
Nervous System, Relief ModelRelief model in 1/2 natural size. Provides a schematic representation of the central and peripheral nervous system. Not divisible.
Newton’s g-ball
Newton’s g-ballThe ball contains a digital stopwatch that can show the time between 0.01-29.99 seconds. Hold down the key and the time will reset. Timing starts when you release the ball and stops when it hits the ground / floor. The mechanics are well protected and the screen is sharp, but the ball must land on a soft surface such as a pad/mat/turf. Maximum drop height is approx. 12 m, friction against air is about 5%.
Ninja balls, seismic accelerator
Ninja balls, seismic acceleratorNinja Balls are a set used to demonstrate the concept of momentum transfer in a simple and visually compelling way. When the set is dropped from a low height, you can observe how the kinetic energy is transferred through the balls, causing the top ball to bounce significantly higher than its starting point. The set consists of five balls and a pair of plastic safety glasses, which should be worn during the experiment to protect your eyes.

Optical rail, 60 cm
Optical rail, 60 cmProfiled rail for extending an optical bench or as a standalone profiled rail for mounting saddles. Can be used as a base for installations requiring fixed spacing, as a measuring set-up for radioactivity measurements, etc. Made from black anodised aluminium. Features a ruler on the side.
Optical table
Optical tableOptical table with inclined top for projecting parallel beams of light from 280020 Student lamp with 3-slit aperture attachment.
Ovary, cross-section, microscope slide
Ovary, cross-section, microscope slideSingle slide of an ovary showing the structures and cells that play a role in a woman’s follicle maturation and ovulation. The appearance of a micro-slide of the ovary is very similar to the illustrations you see in a biology book, so it does not require any medical training to find the structures and cells you have read about.
