"micro tube racks"

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.

The high-frequency coil can be used to test vacuum equipment for leakage or excite electrical tubes for demonstrations.

The Air Core Solenoid is perfect for induced magnetic field studies.

Build five different power supplies by connecting clip leads to one of the five color-coded terminals.

A simple tool for communicating complex workings of electricity, this plastic battery holder is fitted with three banana plug jacks.

Spare pith balls for pith ball electroscope.

This real animal fur is for use in electrostatic experiments.
