Biology
Ovary, cross-section, microscope slide
Single 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.

Chemistry
Periodic System poster 120×85 cm
Double-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.

Chemistry
Periodic table with cast elements
Periodic table in compact acrylic block with 83 pure elements embedded – a visual and cool way to study elements and groups. Radioactive elements are (except for thorium and uranium) omitted for safety reasons. The gaseous elements are represented as microbubbles in acrylic. An identification list and certificate of authenticity are included.

Biology
Photosynthesis lamp, LED, full spectrum, 20 W
This full-spectrum LED light is designed for classroom plant experiments. It features two flexible arms with adjustable heads, a clamp for attaching to a table edge or windowsill, and a timer function that can be set to 3, 6, or 12 hours. The light spectrum mimics sunlight in the 380–800 nm range, and the brightness can be adjusted in ten levels. The light operates on 100–240 V and supports plant experiments all year round.

Physics
Physical pendulum/Bessel pendulum
The 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.
