Highly evacuated electron tube with focusing electron gun and fluorescent screen inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using the Helmholtz coil pair (not included). By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge (e/m) and the velocity of the electrons.

Learn about the formation of crystals and how they play a role in the rock cycle.

Learn about thin layer chromatography, an analytical tool to separate similar compounds.

Learn about cholesterol levels and how they can have a major impact on your health and your risk of heart disease.

Learn about amino acids, the building blocks of proteins, and how to separate and identify them using paper chromatography.

Consists of one support, 5 plumb lines, 1 roll of tape, and 5 figures (triangle, L, trapezoid, parallelogram, parallelopiped). This kit helps students in the individual research of the center of gravity of a flat body, the conservation of the result on paper, the possibility of a graphic verification, and the discovery of the geometric research method.

Keep Students’ Interest in the Water Cycle from Evaporating

The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.
