       Migration cells assembly [See Section 10]

       Constant voltage power supply - output: 0-30V DC; capacity: 0-2A

       Digital voltmeter: measurement of DC potentials in the 12-24 volts range and current intensity, to 0.1 mA accuracy in the 0-200 mA range and 0.01A accuracy in the 0.2-1 A range.

       Electrically conductive wires to connect the power supply output to the electrodes through jacks attached to the test cells. The electrical resistance of each wire should be less than 0.01 Ohm.

       Measuring probes for insertion through the small holes in the cells to measure potential difference between the specimen. One probe's extremity is connected to the jack on the voltmeter.

       Vacuum saturation apparatus (vacuum pump, container, pressure gauge, etc.)

       Sizing specimen apparatus (rulers)

       Balance (repeatability: 0.01g)

       Funnel and containers (made of chemical-resistant materials)
