Rapid E-Field Apparatus - 150 x 150 x 60mm

This apparatus is ideal for demonstrating electric fields between various electrodes. Liquid paraffin is placed in the 90mm diameter petri dish and semolina or fine grass seed is sprinkled on the surface. Various electrode configurations can be arranged in the liquid and when a high voltage is applied via the 4mm terminals the field pattern is generated. The see-through base allows the pattern to be projected via an overhead projector system.

• Supplied without paraffin or semolina
• Dimensions (L x W x H): 150 x 150 x 60mm
• Petri dish 90mm diameter
