"SCIENTIFIC hach"

Radiometer with four lightweight metal arms.

This Ray Box is a simple, safe, and sturdy source of projected light for many classic optics experiments. Best of all, you don't need a completely dark room to conduct optic experiments due to its high-intensity light!

The rolling friction car kit provides four cars for exploration into the force of friction. Each car provides a set of different material wheels (wood, fabric, soft rubber, soft silicone) with a different coefficient of friction. By setting the cars in motion with equivalent velocities, one can qualitatively demonstrate the frictional properties of rolling without slipping.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.
